Q: Make sure that the a or x2 term is positive. Here's how you do it: 2x2 - 9 = 12x = 2x2 - 12x - 9 = 0 In this equation, the a term is 2, the b term is -12, and the c term is -9. The constant term is the numerical term without a variable. Move it to the right side of the equation: 2x2 - 12x - 9 = 0 2x2 - 12x = 9 If x2 has no term in front of it, and just has a coefficient of 1, then you can skip this step. In this case, you'll have to divide all of the terms by 2, like so: 2x2/2 - 12x/2 = 9/2 = x2 - 6x = 9/2 The b term in this example is -6. Here's how you do it: -6/2 = -3 = (-3)2 = 9 = x2 - 6x + 9 = 9/2 + 9 Factor the terms on the left side to get (x-3)(x-3), or (x-3)2. Add the terms on the right side to get 9/2 + 9, or 9/2 + 18/2, which adds up to 27/2. The square root of (x-3)2 is simply (x-3). You can write the square root of 27/2 as (27/2). Therefore, x - 3 = (27/2). and solve for x. To simplify (27/2), look for a perfect square within the numbers 27 or 2 or in their factors. The perfect square 9 can be found in 27, because 9 x 3 = 27. To take 9 out of the radical sign, pull out the number 9 from the radical, and write the number 3, its square root, outside the radical sign. Leave 3 in the numerator of the fraction under the radical sign, since that factor of 27 cannot be taken out, and leave 2 on the bottom. Then, move the constant 3 on the left side of the equation to the right, and write down your two solutions for x: x = 3 + 3(6)/2 x = 3 - 3(6)/2)
A: Move all of the terms to one side of the equation. Move the c term or constant to the other side. Divide both sides by the coefficient of the a or x2 term. Divide b by two, square it, and add the result to both sides. Simplify both sides. Find the square root of both sides. Simplify the radical

Q: Calcium can help prevent and reduce the pain you have associated with your period, as well as many other PMS symptoms. Calcium can be consumed through items such as: dairy products, fortified soy beverages, canned salmon and sardines, and leafy greens. You can also take additional calcium via a calcium supplement of between 500 mg and 1,200 mg per day. Low magnesium levels can be associated with many PMS symptoms, including cramps and headaches. Increase the amount of foods you consume that are high in magnesium, such as: sunflower seeds, nuts, lentils, legumes, whole grains, soybeans, figs and green vegetables. You can also increase your magnesium intake by taking magnesium supplements in a pill form. For the best effect, take 360 mg per day for three days before your period begins. Vitamin B6 helps produce serotonin. Serotonin can help reduce anxiety and depression brought on by PMS. Foods with high amounts of vitamin B6 are: beef, pork, chicken, fish, whole grain cereals, bananas, avocados, and potatoes. While vitamin B6 is found in supplements, but be careful not to take more than 100 mg per day. Excess vitamin B6 can be toxic. Vitamin D helps your body absorb calcium and can act as an anti-inflammatory. Try taking 400 IU per day to help reduce the pain you have due to your period. Vitamin E has been shown to decrease pain associated with your period when 500 IU is taken per day. It is best to start taking the vitamin E supplements two days before your period begins, and stop three days after your period has started. Therefore you'd be taking it for five days. Omega-3 fatty acids are most often found in fish oil as a supplement. It can be taken in pill form or liquid form. Fish oil is an anti-inflammatory and can help reduce the pain associated with your period. Several types of herbal teas contain ingredients that can help reduce the painful cramps brought on by your period. Raspberry leaf tea can help to relax your uterus and reduce cramping. Chamomile tea contains an anti-spasmodic which can also reduce cramping. Cramp bark tea (made using 1 teaspoon of dried cramp bark simmered in 1 cup of water for 15 minutes) can help reduce pain. It can be taken up to three times a day. Evening primrose oil can be obtain both in liquid form and in pill form. It contains an essential fatty acid called gamma linolenic acid (GLA). GLA blocks prostaglandins in your body which can cause painful cramps during your period. For the best effects, take 500 to 1,000 mg per day. Taking ginger supplements in extract form (specifically Zintoma or Goldaru) can help reduce the pain associated with your period. Take 250 mg four times a day for the first three days of your period.
A:
Increase your calcium intake. Add more magnesium to your diet. Boost your vitamin B6 levels. Take vitamin D supplements. Try vitamin E supplements. Supplement omega-3 fatty acids. Make herbal tea. Give evening primrose oil a try. Use ginger supplements.
