Question

Simplify 8y(y - 4) + 3y(y + 2).

Answer 1

= 8y^2 - 32y + 3y^2 + 6y

= 11y^2  - 26y

Answer 2

Hey!

Let's write the problem, 
$8y\left(y-4\right)+3y\left(y+2\right)$
Apply the distributive property on the left side.
$=8y^2-32y+3y\left(y+2\right)$
Apply the distributive property on the right side.
$=8y^2-32y+3y^2+6y$
Add like terms.
$=11y^2-26y$
We have successfully finished simplifying the expression. 

Thanks!
