Simplify completely x^2+7x-30 divided by x+10

x-3

Step-by-step explanation:

1) look at the top equation and factor:

Factors of -30: 10,-3    6,-5   15,-2  -3,10  -6,5   -15,2

Factors adding up to 7: 10,-3

So x^2+10x-3x-30

X(x+10)      -3(x+10)

(x-3)(x+10)

2) bring in the denominator terms

(x+10)'s cancel each other out

And your left with (x-3)

Hope this helps!
