Question

Rectangle A has an area of 4 − x2. Rectangle B has an area of x2 + 2x − 8. In simplest form, what is the ratio of the area of Rectangle A to the area of Rectangle B? Show your work.

Answer 1

area of A : area of B.
4-x^2 : x^2 + 2x-8
(2+x)(2-x): (x+4)(x-2)
-x-2 : x+4

Answer 2

or -(x-2)/(x+4)
