x = -b (b2 - 4ac)---------------------2a We obtain the expression:x = -4 (42 - 411) / 2 You should get two x values. As shown above, we obtain two answers: x = -2 + (3) or x = -2 - (3) Plug the x values you obtained into two polynomial expressions as the constants. These will be your factors. If we call our two answers h and k, we're writing two factors like so:(x - h)(x - k) In this case, our final answer is:(x - (-2 + (3))(x - (-2 - (3)) = (x + 2 - (3))(x + 2 + (3))

Summary: Plug the corresponding values into the quadratic formula: Solve for x. Use your value for x to figure out the factors.

These snap over the brick without the use of nails. However, the brick and clamp must be a very similar height to make a good fit. This may not work well if the recess above the brick leaves less than 1/8 inch (3.18 mm) depth of the brick's upper surface exposed, or if it forms a curved surface due to a concave masonry joint. As long as the masonry is not too old and soft, you can replace nails with screws for more secure anchoring: Choose screws at least twice as long as the thickness of the lumber you are attaching. Select a masonry drill bit with a diameter equal to the screw's shaft's, not including the threads. Drill through the lumber and into the masonry. Insert and tighten the screw until firm. Avoid over-tightening. There are many epoxies, mastics, and contact cements that can bond to brick. Check the manufacturer's instructions before buying to find a product that works with the material you plan to attach, and that can withstand the expected temperature, weight, and weather exposure. This approach may work well for light loads on soft brick surfaces, which are difficult to drill or nail without crumbling. This tool drives hardened steel pins into the masonry using a gunpowder charge. It is rarely used for home projects, since lack of training or the wrong model could lead to shattered brick or injury. If you have some construction experience and have a large project to complete, this could save you a lot of time. Do not use a powder-actuated tool on hollow brick.

Summary: Hang pictures from hole-free brick clamps. Install masonry screws. Use an adhesive substance. Complete professional jobs with a powder-actuated tool.

Pour a bottle or can of beer into a jug or bowl and let it sit overnight or throughout the day. The more air surface your beer is exposed to, the faster it will oxidize and become flat. Beer becomes flat by releasing the carbon dioxide it creates. It's important that the carbon dioxide is gone from the beer when using it to treat hair as carbon dioxide combined with water can create hard water or water with a high mineral content. The presence of carbon dioxide can hinder the effects of shampoos and make it harder for you to wash your hair effectively. As well, hard water causes the scales on each hair to stand up, making your hair look tangled and tough. Use whatever shampoo you normally use but skip the conditioner. The beer will act as your conditioner instead. You can transfer your flat beer into a closed container or bottle and bring it with you into the bathroom or somewhere you can easily reach for while in the shower. Pour the container or bottle of beer onto your hair and lather it into your scalp. Beer is also very beneficial for your skin as beer sediment or brewer's yeast helps reduce sebum production and control oily skin on your face or scalp. You can also try dipping the ends of your hair with beer first, letting it set in your hair for about 5 minutes before rinsing your entire head with beer. It's recommended you don't rinse the beer off completely and leave it in your hair for a better effect. Towel dry your hair afterwards. It may take a few washes before you can feel and see results. It's best to only do the beer wash a few times a week as it can be quite drying for hair if used everyday.

Summary: De-carbonate your beer. Shampoo your hair. Massage your hair with beer for 1 minute. Rinse the beer off.

If you're going to use a straightening or curling iron on your hair daily, it's important that to select one that's made with a material that will do the least damage to your hair. Inexpensive irons are usually made with metal that doesn't heat evenly so it can easily burn your hair. You'll pay more for an iron made with a higher quality material, but it will help minimize damage. Ceramic irons heat quickly and evenly, so they're not as likely to burn your hair. They also produce negative ions that help smooth cuticle and boost shine. Be sure to choose an iron that's made of ceramic and not just coated with it. A ceramic coating will eventually wear off over time. Tourmaline irons can produce 6 times the amount of negative ions that ceramic models do. As a result, you're left with smooth, shiny, healthy looking hair. Titanium irons are usually the most expensive, but they heat quickly and evenly. They're a particularly good option for thick or coarse hair. Many straightening and curling irons only have low, medium, and high heat settings. To keep your hair from getting damaged, you want to use the lowest heat possible to give you your desired style. That's why it's best to purchase an iron with digital heat controls that allow you to choose a specific temperature to heat to. In general, an iron that allows you to set the temperature between 175 degrees to 400 degrees Fahrenheit (80 degrees to 200 degrees Celsius) is sufficient for all hair types. The finer or thinner your hair is, the lower the temperature on your iron should be. Start at 175 degrees (80 degrees Celsius), and only raise the temperature if your hair isn't curling or straightening properly. No matter how thick or coarse your hair is, you should never set your iron to higher than 400 degrees Fahrenheit (200 degrees Celsius). The size of your straightening or curling iron can also affect how damaged your hair becomes. If you use a larger iron, you're less likely to need to go over the same section of hair twice to curl or straighten it properly. In general, a 1-inch (23-mm) curling or straightening iron is the most versatile for all hair types. If you have a shorter hair, you may want to use a smaller iron. If you have extremely thick or long hair, you may want to use a larger iron. When it comes to curling iron, it's also important to consider the hairstyle that you're going for. If you want tight ringlet curls, you'll want to use a smaller curling iron. If you want loose waves, you'll want to use a larger curling iron.
Summary: Use an iron made of a high quality material. Opt for an iron that has adjustable temperature controls. Consider the size of your iron.
