yup. =) Do you get why though?

anonymous · Answer

No. Pretty much all of math confuses me.

anonymous · Answer

oh lol. Sorry for not explaining. Basically when you factor this: you get

(5x+3)^2. And to get that, you have to make sure two numbers multiply up to the last term, and add up to the term in the middle. Since the area of a square is side x side, take the square of the answer, and you have the measurement for one side =) Confused?
