3 answers

-rearrange to group like terms:

3x^2 - 4x^2 + 5x - 2x + 6 + 9

-combine like terms:

-x^2 + 3x + 15

Therefore, the simplified expression is -x^2 + 3x + 15.
simplify 4x^2+8x-11x+6-5x^2+2
-rearrange to group like terms:

4x^2 - 5x^2 + 8x - 11x + 6 + 2

-combine like terms:

-x^2 - 3x + 8

Therefore, the simplified expression is -x^2 - 3x + 8.
