Question

Simplify the expression. 3(2y - 8) - 2y(5 - y)

Answer 1

Answer:

2y^2 -4y -24

Step-by-step explanation:

start by expanding the first term, also known as multiplying the 3

3(2y-8) to get 6y-24

then -2y and (5-y) to get -10y and 2y^2

(dont forget to include the negatives when mulitiplying it out)

then combine like terms to get

2y^2 - 4y - 24

Answer 2

Answer:

2( y^2 - 2y - 12).

Step-by-step explanation:

3(2y - 8) - 2y(5 - y)

Distribute the 3 and the -2y over the parentheses:

= 6y - 24 - 10y + 2y^2

= 2y^2 - 4y - 24

= 2( y^2 - 2y - 12).
