In math class, we are learning the  way how to FOIL something (First Outer Inner Last). There are many steps you must take to be able to complete the equation. The problems look like this: (x+4)(x+7). First, you multiply the first “x” (x+4)(x+7) by the other “x” in the problem (x+4)(x+7). Then, that equals “x” to the second power which looks like this: 

After that, you are going to multiply the first “x” (x+4)(x+7) by the seven (x+4)(x+7). That equals 7x. Next you are going to multiply the 4 (x+4)(x+7) by the second “x” in the problem (x+4)(x+7). That equals 4x. Now you are going to multiply the 4 (x+4)(x+7) by the seven (x+4)(x+7) which equals 28. Now, you are going to add all of the answers together in order of how you solved them, to make one big equation. “x” to the second power+7x+4x+28=? The answer will look like this: “x” to the second power+11x+28. Here is another problem in picture form that might help you understand it more:
