Let's simplify step-by-step.
−7x2−6x+9−7x2−6x+9
=−7x2+−6x+9+−7x2+−6x+9
Combine Like Terms:
=−7x2+−6x+9+−7x2+−6x+9
=(−7x2+−7x2)+(−6x+−6x)+(9+9)
=−14x2+−12x+18
Answer:
=−14x2−12x+18
Let's simplify step-by-step.
−3x2−x+7−3x2−x+7
=−3x2+−x+7+−3x2+−x+7
Combine Like Terms:
=−3x2+−x+7+−3x2+−x+7
=(−3x2+−3x2)+(−x+−x)+(7+7)
=−6x2+−2x+14
Answer:
=−6x2−2x+14
Answer: -10x^2-7x+16
Step-by-step explanation: (-7x^2-6x+9)+(-3x^2-x+7)
-7x^2-6x+9-3x^2-x+7
Nothing to distribute.
