2.
4x2 + 4 – 5x + x – 2x2 + 8
(1 point)
· –2x2 + 4x + 12
· –2x2 – 4x + 12
· 2x2 + 4x + 12
· 2x2 – 4x + 12

Answer 1

To simplify the polynomial 4x^2 + 4 - 5x + x - 2x^2 + 8, first rewrite it to put all the like terms next to one another: 4x^2 - 2x^2 - 5x + x + 4 + 8. Then, add together these like terms: 2x^2 - 4x + 12. So, the correct answer will be the last option.
