Factor out the greatest common monomial factor from the polynomial $60 t ^ { 2 } - 75$.
A) $15 t ( 4 t - 75 )$
B) $75 \left( 60 t ^ { 2 } - 1 \right)$
C) $60 t ( t - 75 )$
D) $15 \left( 4 t ^ { 2 } - 5 \right)$
E)no common factor other than 1

Question

Quizplus · Accepted Answer

The greatest common factor (GCF) of 60 and 75 is 15, and $t^2$ can only be factored out where it appears, so the correct factorization is $15(4t^2 - 5)$.
