(2x^2 + 4x + 6) - (-3x - 5x^2 + 4)

The negative sign separating the expressions is just multiplying the rightmost expression by -1.

(2x^2 + 4x + 6) + (3x + 5x^2 - 4)

Now, let's add together terms that share the same variable.

2x^2 + 5x^2 = 7x^2

4x + 3x = 7x

6 + (-4) = 2

Let's combine each of these terms into one expression.

7x^2 + 7x + 2 is the final answer.
