Factor by grouping. -12x² - 20xy + 15xy - 25y² A) ( 4x + 5y)( 3x - 5y) B) ( 4x + 5)( 3x - 5) C) ( 12x + 5y)(x - 5y) D) ( 4x - 5y)( 3x - 5y)

Question

Quizplus · Accepted Answer

The correct factoring by grouping is done by first grouping the terms as (12x^2 - 20xy) + (15xy - 25y^2), then factoring out common factors from each group to get 4x(3x - 5y) + 5y(3x - 5y), and finally factoring out the common binomial factor to get (4x + 5y)(3x - 5y).
