Choose the correct simplification of the expression (-2x + 8y)(9x - 3y).
-18x2 + 78xy - 24y2
18x2 + 78xy - 24y2
-18x2 - 78xy + 24y2
-18x2 + 72xy - 24y2
Solution:
Given expression (-2x + 8y)(9x - 3y)
According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
By using distributive property, we get
⇒ -18x2 + 6xy + 72xy - 24y2
⇒ -18x2 + 78xy - 24y2
The correct simplification of the expression (-2x + 8y)(9x - 3y) is -18x2 + 78xy - 24y2.
Choose the correct simplification of the expression (-2x + 8y)(9x - 3y).
Summary:
The correct simplification of the expression (-2x + 8y)(9x - 3y) is -18x2 + 78xy - 24y2.
