Question

Please help! Simplify:
x^2-9/x^2-6x+9

Answer 1

\[\frac{x^2-9}{x^2-6x+9}\]
First, factor the top and the bottom into a product of binomials. This is usually the first step in these types of problems.
\[\frac{(x+3)(x-3)}{(x+3)(x+3)}\]
The x+3 term in the numerator will cancel with one in the denominator.
\[\frac{x-3}{x+3}\]
