To simplify the equation combine the like terms:
-2x^2 - 10x^2 = -12x^2
3-10 = -7
The simplified expression is -12x^2 + 5x - 7
-2x² + 3 + 5x - 10 - 10x²
Collect the like terms
-12x² + 3 + 5x - 10
Calculate the difference
-12x² - 7 + 5x
Use the commutative property to reorder the terms
-12 + 5x -7
Collect the like terms
-12x² + 3 + 5x - 10
