Answer:
− 5 x ^2 + 13 x − 18
Negative five x squared, plus thirteen x minus eighteen.
Step-by-step explanation:
Let's simplify step-by-step.
(−2x^2 + 4x − 6)−(3x^2 −9x + 12)
Distribute the Negative Sign:
= (−2x^2 + 4x −6 +)−1(3x^2 −9x + 12)
= (−2x^2 + 4x + −6 +)−1(3x^2)+−1(−9x)+(−1)(12)
= −2x^2 + 4x + −6 + −3x^2 + 9x + −12
Combine Like Terms:
= −2x^2 + 4x + −6 + −3x^2 + 9x + −12
= (−2x^2 + −3 x 2)+(4x + 9x)+(−6 + −12)
= −5x^2+13x+−18
Answer:
= −5x^2 + 13x − 18
