Answer 1

Simplify each expression.
9. 3x^2-4x-2x^2-5x
10. -2d+7+5d+8
11. 3(2r+4r^2-7r+4r^2)
12. -2(m+1)+9(4m-3)
13. 6(a-3a^2-2a-3a^2)
14. s-4-(s^2-2)-8s

Answer 2

9) 3x^2 - 2x^2 - 4x - 5x => x^2 - 9x => x(x - 9)

Answer 3

10) -2d + 5d + 7 + 8 => 3d + 15

Answer 4

For 9) I would stop at \(x^2 - 9x\)
