Question

Preform the operation
(−4x 2 +2)−(−7x 2 +10x+1)

Answer 1

-4x + 1

Explanation:

( −4x 2 +2 ) − ( −7x 2 + 10x + 1 )

(-4x) (2) + 2 + -1 (-7x) (2) + -1 (10x) + -1 (1) <--- First let's distribute

-8x + 2 + 14x + -10x + -1

(-8x + 14x + -10x) + (2 + -1) <---- Now combine like terms

-4x + 1 <--- Final Answer :)

Answer 2

3x² - 10x + 1

Explanation:

(−4x 2 +2)−(−7x 2 +10x+1)

-4x² + 2 + 7x² - 10x - 1

-4x² + 7x² - 10x + 2 - 1

3x² - 10x + 1
