Question
I don't understand factoring. One of my homework questions asks for that. The question is "The area of a rectangular garden is given by the trinomial x to the 2nd power plus x -42. What are the possible dimensions of the rectangle? Use factoring.

why all the words?
a = x^2+x-42
Factor that to get
a = (x+7)(x-6)
a = x^2+x-42
Factor that to get
a = (x+7)(x-6)
