In one sentence, describe what the following article is about: Birds thrive in large cages, so opt for the largest cage that your housing space can accommodate. A general rule of thumb is that the width of the cage should be at least twice the wingspan of your bird. For some birds, being able to fly short distances within the cage may be an important part of ensuring it has a healthy living space. Some other fairly standard requirements include: The cage bars should not be too small; the bird's talons might get caught on or in them if the bar wires or lengths are too small. Equally, the bars should not be so large that the head of the bird could get trapped or the bird could squeeze through and escape. The bigger the space in the cage, the better. Although bird cages that are bigger tend to be harder to clean and are more expensive, if you are not in the house often or don't have time to take the bird out for exercise, space in their cage is critical. Small cages can lead to behavior problems. Circle cages are bad for the bird. There is hardly any space for the bird, and no corners to feel safe in. Moreover, the circle tends to cause the bird to twist its head; the bird can develop behavioral problems from the constant turning and turning. Do not buy guillotine-styled doors, since they are easier for the bird to escape from. Never house more than one bird in a small cage. Birds need space to retreat, forage, fly and be apart from other birds, so the more birds being kept, the larger the cage must be. Aviaries (large cages that are akin to small sheds) are more appropriate for keeping several birds at the same time. If keeping different species of birds, you'll need to be sure that the animals are compatible when placed together. Cages should be kept indoors, and in a room with frequent traffic. Birds are social animals, and will become unhappy if isolated in a room. Also remember that you'll be cleaning out the cage frequently, so hang it somewhere that you can access easily. Birds in hanging cages can often be transported outdoors to hang under a porch or similar place for daytime fresh air. Always remember to bring the bird back in before cool evening breezes and night air arrive. The location of the bird's cage will also be affected by the bird's personality. While a very social bird might love being the center of attention and seeing constant human traffic, a more nervous bird might be happier kept somewhere quieter and away from hustle and bustle (but still being able to interact with the family). Nervous birds may do better in the corner of a room or in an area with the back of their cage partially covered. Avoid placing a cage in front of a window permanently. The bird will be on the constant lookout for "enemies," which can cause it to feel nervous. Putting a cage against a wall can give the bird a break from worrying about predators. This makes cleaning much easier, and the papers can be disposed of with ease, then fresh ones placed straight down for the next day's use. Keep a supply of papers hand; junk mail and old newspapers also work well. If you prefer a more traditional method of lining your bird's cage for waste removal, line the bottom of the cage with wood chips, kitty litter, or sand.
Summary: Purchase a large cage for housing the bird. Choose a rectangular cage for your bird. Ensure that the space is more than adequate if housing more than one bird. Ensure that placement of the cage is somewhere warm and comfortable. Place some old magazines papers on the bottom of the cage.

In one sentence, describe what the following article is about: When solving an equation with binomials, especially complex binomials, it can seem like there is no way everything will match. For example, try to solve 5y2y2=3y{\displaystyle 5y-2y^{2}=-3y}. One way to solve it, especially with exponents, is to factor first. Practice Problem: 5y2y2=3y{\displaystyle 5y-2y^{2}=-3y} Remember that binomials must only have two terms. If there are more than two terms you can learn to solve polynomials instead. This whole strategy relies on one of the most basic facts of math: anything multiplied by zero must equal zero. So if you equation equals zero, then one of your factored terms must equal zero! To get started, add and subtract so one side equals zero. Practice Problem: 5y2y2=3y{\displaystyle 5y-2y^{2}=-3y} Set to Zero: 5y2y2+3y=3y+3y{\displaystyle 5y-2y^{2}+3y=-3y+3y} 8y2y2=0{\displaystyle 8y-2y^{2}=0} At this point, you can pretend the other side doesn't exist for a step. Just find the greatest common factor, divided it out, and then create your factored expression. Practice Problem: 5y2y2=3y{\displaystyle 5y-2y^{2}=-3y} Set to Zero: 8y2y2=0{\displaystyle 8y-2y^{2}=0} Factor: 2y(4y)=0{\displaystyle 2y(4-y)=0} In the practice problem you are multiplying 2y by 4 - y, and it must equal zero. Since anything multiplied by zero equals zero, this means either 2y or 4 - y must be 0. Create two separate equations to figure out what y must be for either side to equal zero. Practice Problem: 5y2y2=3y{\displaystyle 5y-2y^{2}=-3y} Set to Zero: 8y2y2+3y=0{\displaystyle 8y-2y^{2}+3y=0} Factor: 2y(4y)=0{\displaystyle 2y(4-y)=0} Set both parts to 0: 2y=0{\displaystyle 2y=0} 4y=0{\displaystyle 4-y=0} You might have one answer, or more than one. Remember, only one side has to equal zero, so you might get a few different values of y that solve the same equation. For the end of the practice problem: 2y=0{\displaystyle 2y=0} 2y2=02{\displaystyle {
rac {2y}{2}}={
rac {0}{2}}} y = 0 4y=0{\displaystyle 4-y=0} 4y+y=0+y{\displaystyle 4-y+y=0+y} y = 4 If you got the right values for y then you should be able to use them to solve the equation. It is simple as trying each value of y in place of the variable, as shown. Since the answer were y = 0 and y = 4: 5(0)2(0)2=3(0){\displaystyle 5(0)-2(0)^{2}=-3(0)} 0+0=0{\displaystyle 0+0=0} 0=0{\displaystyle 0=0} This answer is correct 5(4)2(4)2=3(4){\displaystyle 5(4)-2(4)^{2}=-3(4)} 2032=12{\displaystyle 20-32=-12} 12=12{\displaystyle -12=-12} This answer is also correct.
Summary:
Use factoring to simplify equations and make them easier to solve. Add and subtract so that one side of the equation is equal to zero. Factor the non-zero side just like normal. Set both inside and outside the parenthesis as equal to zero. Solve both equations for zero to get your final answer or answers. Plug your answers back in to ensure that they work.
