Question

FACTORIZE WITH H.C.F METHOD

Answer 1

4ax^2+12ax+9a
=4ax^2+6ax+6ax+9a
=2ax(2x+3)+3a(2x+3)
=(2x+3)(2ax+3a)
=a(2x+3)(2x+3)

Answer 2

Hi friends

Here is your answer
$4a {x}^{2} + 12ax + 9a \\ \\ = a(4 {x}^{2} + 12x + 9) \\ \\ = a(4 {x}^{2} + 6x + 6x + 9) \\ \\ = a(2x(2x + 3) + 3(2x + 3)) \\ \\ = a(2x + 3)(2x + 3)$
Hope it helps you
