Ok thanks for the heads up

Answer 7

Y(y+4)-y(y-3)-9y

Answer 8

you used the distributive property

Answer 9

Distribute:
y(y+4) - y(y-3) -9y
=> y^2 + 4y - y^2 +3y - 9y
=> 7y-9y
=> -2y

Answer 10

thanks for the short explanation

Answer 11

You could also factor out y:
y(y+4) - y(y-3) -9y
y (y+4-y+3-9)
y(7-9)
-2y
