Question

Simplify:

x² + 3x - 3x² - 4x

I need help knowing the process of this problem, so I can figure it out​

Answer 1

-2x²-x

Explanation:

x² + 3x - 3x² - 4x

You need to simplify

x² -3x²=-2x²

and

`3x - 4x = - x`

Answer 2

Explanation:

Let's combine the like terms first, which are x^2 & -3x^2, and 3x & -4x.

x^2 -3x^2 is -2x^2. 3x -4x is -x.

The final, simplified expression would be -2x^2 -x.
