so, split 12ab = 3ab and 9ab

\(a^2+3ab+9ab+27b^2 \)
factor out a from 1st 2 terms and 9b from last two, what u get ?

Answer 9

This is what I have so far . . .
a2 + 12ab + 27b^2
3*9 = 27
3 + 9 = 12
(ab + 3) (ab + 9)??

Answer 10

\(a^2+3ab+9ab+27b^2 = a(a+3b)+9b(a+3b)\\= (a+3b)(a+9b)\)
got this ?
