Answer:
(x^3+3x^2+x+1)+(2x^3-2x^2-2x+2)
3x^3 + x^2 - x + 3
I think I simplified it completely. Hope this helps! Good luck! :)
Answer:
The sum = 3x³ + x² - x + 3
Step-by-step explanation:
It is given that,
(x³ + 3x² + x + 1) + (2x³ - 2x² - 2x + 2)
To find the sum
(x³ + 3x² + x + 1) + (2x³ - 2x² - 2x + 2)
= x³ + 2x³ + 3x² - 2x² + x - 2x + 1 +2
= 3x³ + x² - x + 3
Therefore the sum = 3x³ + x² - x + 3
