Question 127508: I am having trouble simplying the following. I have come up with two solutions and need help to see if I am on the right track. Thanks in advance for your help.
Simplify: 2y^2-4/5y-y+3y^2
Solution #1:
= (2y^2+3y^2)+(-4/5-1)y
= 5y^2+(-4/5-5/5)y
= 5y^2-9/5y

Solution #2:
= (2y^2)^5-(4/5y)^5-(y)^5+(3y^2)^5
= 32y^2-4y-5y+243y^2
= 275y^2-9y
= y(275y-9)

2y^2-(4/5)y-y+3y^2 I assume this is the problem.
5y^2-(9y/5)
(25y^2-9y)/5
y(25y-9)/5
