Factories the following polynomials.

$(a) 6 p (p - 3) + 1 (p - 3)$
$(b) 14 (3 y - 5 z)^{3} + 7 (3 y - 5 z)^{2}$

Open in App

Solution

$(a) 6 p (p - 3) + 1 (p - 3) = (p - 3) (6 p + 1)$

$(b) 14 (3 y - 5 z)^{3} + 7 (3 y - 5 z)^{2}$

$= 7 (3 y - 5 z)^{2} [2 (3 y - 5 z) + 1]$

$= 7 (3 y - 5 z)^{2} (6 y - 10 z + 1)$
