Rectangle A has an area of 9 − x2. Rectangle B has an area of x2 + x − 12. In simplest form, what is the ratio of the area of Rectangle A to the area of Rectangle B? Show your work.
\[Ratio=\frac{ Area~of~rectangle~A }{ Area~of~rectangle~B }\] \[=\frac{ 9-x^2 }{ x^2+x-12 }\] Try to factorise the numerator and denominator nd cancel the common factors. Can u do @KiArUnsYu?
