I am learning factoring by grouping and I did these two questions and just want to make sure I have the right answer

OpenStudy (waheguru):

\[4ab^2-12a^2b=3bc+9ac\] = \[(b-3a)(4ab-3c)\]

OpenStudy (anonymous):

try foiling it and if it equals you got it right

OpenStudy (waheguru):

\[4x^2+6xy+12y+8x\] = \[(x+2)(4x+6y)\]

OpenStudy (waheguru):

box way?

OpenStudy (anonymous):

Yes that is the correct answer
