Simplify 5x - 12y + 8x + 2x2 + 4x2

First, let's simplify by multiplying what needs to be multiplied:

5x - 12y + 8x + 4 + 8

Now we add and subtract where needed:

13x + 12 - 12y

The answer is "6x²+13x-12y."

You can start to simplify this by separating the equation into like terms.

1. 2x²+4x²=6x²

2. 5x+8x=13x

3. - 12y

Then put the expression back together.

6x²+13x-12y
