See a solution process below:

First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly:

$y + 5 + 2y + 4y^2 - 2$

Next, group like terms:

$4y^2 + 2y + y + 5 - 2$

Now, combine like terms:

$4y^2 + 2y + 1y + 5 - 2$

$4y^2 + (2 + 1)y + (5 - 2)$

$4y^2 + 3y + 3$

How do you find the sum or difference of (y+5)+(2y+4y^2-2)(y+5)+(2y+4y^2-2)?
