= (6x² + 7x + 2)- (-9x² -10)
= 6x² + 7x + 2 + 9x² +10
= 9x² + 6x² + 7x +10 + 2
= 15x² + 7x +12
Answer:
15x^2+7x+12
Step-by-step explanation:
Distribute the Negative Sign:
=6x2+7x+2+−1(−9x2−10)
=6x2+7x+2+−1(−9x^2)+(−1)(−10)
=6x2+7x+2+9x^2+10
Combine the terms:
6x2+7x+2+9x2+10
=(6x2+9x2)+(7x)+(2+10)
=15x2+7x+12
(All the 2's with the 9 that aren't added(so for example 9x2. That means 9x to the power of 2) are the exponents. I do not know how u write them up on the thing but here u go.)
