Question

simplify: x^2-3x-10/x+2

Answer 1

\[\frac{x^2-3x-10}{x+2}\]
Try factoring the numerator.

Answer 2

On problems like this, the denominator is frequently a factor of the numerator.

So try this: x^2-3x-10 = ( x + 2)* ( ? + ? )

Answer 3

(x+5)?

Answer 4

Close - when there are 2 minus signs in the expanded version (x^2-3x-10), then it usually means that the factorisation contains one plus and one minus.

Answer 5

The foolproof way of checking your answer would be to expand your roots see if it matches. Does (x+2)(x+5)=x^2-3x-10?
