You want to rewrite it out first. $$\large \cfrac{(x^2-12)(x+20)}{(x-10)}$$ Now use the foil or grouping method to solve the numerator

jhannybean · Answer

numerator: $\large (x^2)(x)+(x^2)(20)-(12)(x)-(12)(20)$

Can you simplify this for me?

souvik · Answer

is it$$(x ^{2}-12x+20)/(x-10)$$

jhannybean · Answer

Ah, possibly.

souvik · Answer

if i am right...
you have to factor the numerator first..

jhannybean · Answer

Yep.$$\large \cfrac{(x^2-12x+20)}{x-10}$$ What two numbers multiply to give you 20 and add to give you -12?
