B) $20 x ^ { 2 } - 24 x y - 18 y ^ { 2 }$
C) $20 x ^ { 2 } - 9 x y - 18 y ^ { 2 }$
D) $20 x ^ { 2 } - 9 x y - 9 y ^ { 2 }$

Question

Quizplus · Accepted Answer

The expression is expanded using the distributive property: $(-5x)(-4x) + (-5x)(-3y) + (6y)(-4x) + (6y)(-3y)$, resulting in $20x^2 + 15xy - 24xy - 18y^2$, which simplifies to $20x^2 - 9xy - 18y^2$.

Multiply - (−5x+6y)(−4x−3y)( - 5 x + 6 y ) ( - 4 x - 3 y )(−5x+6y)(−4x−3y)

Multiply
- $( - 5 x + 6 y ) ( - 4 x - 3 y )$
