M'Ahlee simplified the following problem: -10x + 3x2 – 4 – 2x + 3. She got -9x -1 for her answer. Is she correct? If so, show your work and prove that she is correct. If she is incorrect, show your work and provide the correct answer.
She is not correct.
-10x + 3x2 – 4 – 2x + 3
(-10x) +(-2x) = -12x
(-4) + 3 = -1
-12x + 3x2 - 1
