What is the result when 6x^2-13x+12 is subtracted from -3x^2+6x+7?

Question

What is the result when 6x²-13x+12 is subtracted from -3x²+6x+7?

Answer 1

-3x²+6x+7 - 6x²-13x+12

Change all of the terms in the second expression to their opposite signs

6x² becomes -6x²

-13x becomes 13x

12 becomes -12

So the new problem is -3x²+6x+7 + -6x² + 13x -12

Now just combine like terms

-3x² + -6x² = -9x²

6x + 13x = 19x

7 + -12 = -5

So your new answer is -9x² + 19x - 5

Answer 2

-3x² + 6x +7 + -(6x² - 13x +12) =

-9x² + 19x - 5
