Factor out the greatest common factor in the given polynomial. (See Example 1.)
3(2y − l)2 + 7(2y − l)3
Example 1
Factor out the greatest common factor.
(a) 12p − 18q
Solution Both 12p and 18q are divisible by 6, and
(b) 8x3 − 9x2 +15xSolution Each of these terms is divisible by x:
(c) 5(4x − 3)3 + 2(4x − 3)2Solution The quantity (4x − 3)2 is a common factor. Facturing it out gives
