Question

Divide and simplify:
((x^2-16)/(x+7))/((3x-12)/(x^2-49))

Answer 1

start by applying the rule for dividing by fractions, flip the denominator and multiply

\[\frac{(x^2 - 16)}{(x + 7)}\times \frac{(x^2 - 49)}{(3x + 12)}\]

factor the expressions and you'll see common factors...

hope it helps
