need to solve this problem but have no idea where to start
12(a+b)^2 + 29(a+b) + 15
--------------------------------
This is a quadratic equation with (a+b) being the variable.
Let w = a+b
----
Rewrite the equation using "w"
12w^2 + 29w + 15
Factor:
(4w+3)(3w+5)
-----------------------
Rewrite the factors using a+b:
(4(a+b)+3)(3(a+b)+5)
================================
