Question

Subtract x^2 + 6x - 10 from -8x^2 - 3x

Answer 1

- 9x² - 9x + 10

Explanation:

we want to subtract x² + 6x - 10 from - 8x² - 3x , that is

- 8x² - 3x - ( x² + 6x - 10) ← distribute parenthesis by - 1

= - 8x² - 3x - x² - 6x + 10 ← collect like terms

= (- 8x² - x² ) + (- 3x - 6x ) + 10

= - 9x² + (- 9x) + 10

= - 9x² - 9x + 10
