-$$12 x ^ { 2 } + 15 x y - 8 x y - 10 y ^ { 2 }$$
A) $( 12 x - 2 y ) ( x + 5 y )$
B) $( 3 x + 2 y ) ( 4 x + 5 y )$
C) $( 3 x - 2 ) ( 4 x + 5 )$
D) $( 3 x - 2 y ) ( 4 x + 5 y )$

Quizplus · Accepted Answer

The given expression can be factored by grouping as follows: $12x^2 + 15xy - 8xy - 10y^2 = 3x(4x + 5y) - 2y(4x + 5y) = (3x - 2y)(4x + 5y)$.

Factor by Grouping 12x2+15xy−8xy−10y212 x ^ { 2 } + 15 x y - 8 x y - 10 y ^ { 2 }12x2+15xy−8xy−10y2
