Answer:
5x^7 + 4x^6 + 1
Step-by-step explanation:
To solve, all you need to do is collect and combine like-terms (terms with the same variables and powers):
The equation is:
- (3x^7 - 4x^6 + 3) + (2x^7 + 8x^6 -2)
Collect like-terms:
- 3x^7 and 2x^7
- -4x^6 and 8x^6
- 3 and -2
You can rewrite the equation as:
- (3x^7 + 2x^7) + (-4x^6 + 8x^6) + (3 - 2)
Now combine the like-terms:
- 3x^7 + 2x^7 = 5x^7
- -4x^6 + 8x^6 = 4x^6
- 3 - 2 = 1
Substitute the found sums and differences into the equation:
- (3x^7 + 2x^7) + (-4x^6 + 8x^6) + (3 - 2) = 5x^7 + 4x^6 + 1
