Question

Will fan and medal!!!!
(a + 3)^2/a - 3 divided by 5/(a^2 - 9)

Answer 1

when you divide by a fraction, the rule is flip the 2nd fraction and multiply

so the problem becomes

\[\frac{(a + 3)^2}{(a -3)} \times \frac{(a^2 - 9)}{5}\]

factor the quadratic, which is the numerator of the 2nd factor and you'll see a common factor that can be cancelled...

and then its an easy simplification.

hope it helps
