Question

simplify (x^2 -9) / (x^2 +x -6)
The answer is (x-3) / (x-2
Don't know how to get there, needs to show the work

Answer 1

\(a^2-b^2 =(a+b)(a-b)\)
for numerator, your a is x, your b is 3 (since 3^2=9),

Answer 2

for denominator, just factor it to get (x+3)(x-2)

Answer 3

combine them and cancel, you get the answer.

Answer 4

Thanks
