What are the factors of

Vsevolod [243]

For this case we have the following expression:

$12c ^ 2 + cd-6d ^ 2$

Rewriting the expression we have:

$12c ^ 2 + 9cd-8cd-6d ^ 2 =$

Grouping:

$(12c ^ 2 + 9cd) + (- 8cd-6d ^ 2) =$

We draw common factor from each group:

$3c (4c + 3d) -2d (4c + 3d) =\\(3c-2d) (4c + 3d)$

Answer:

$(3c-2d)(4c+3d)$
