Question

Find the sum (x^3+3x^2+x+1)+(2x^3-2x^2-2x+2)

Answer 1

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

Answer 2

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! :)
