Answer:
3y^2-14y+16

Process:
(3y-8)(-2+y)
Use the FOIL on the parentheses
=3y(-2+y)-8(-2+y)
Use the distributive property
=-6y+3y^2+16-8y
Combine like terms
=3y^2-8y-6y+16
=3y^2-14y+16

I hope this helps! Please comment if you have any questions.

1/2 of 4 = 2   4+2=6
1/2 of 3 = 1.5 3+ 1.5=4.5
1/2 of 6 = 3  6+3=9

6 Bananas
4.5 Apples
9 Pears
