Question

Perform the indicated operation and simplify the result.

Answer 1

$\frac{3a^{2}-13a+4 }{9a^{2} -6a+1}$*$\frac{28+7a}{a^{2}-16 }$

$\frac{(a-12)(a-1) }{(3a-1)^{2} }$*$\frac{7(4+a)}{(a+4)(a-4)}$$\frac{(a-12)(a-1) }{(3a-1)^{2} }$*$\frac{7}{(a-4)}$

result = $\frac{(a-12)(a-1)7}{(3a-1)^{2}(a-4)}$
