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

See a solution process below:

#### Explanation:

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

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

Next, group like terms:

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

Now, combine like terms:

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

$4 {y}^{2} + \left(2 + 1\right) y + \left(5 - 2\right)$

$4 {y}^{2} + 3 y + 3$
