Question

What is the sum of the polynomials?
(7x^3– 4x^2) + (2x^3 +3x)

Answer 1

sum of the polynomials is
`9 x^(3) - 4 x^(2) +3x`

Explanation:

Given polynomial is (7 x^3– 4 x^2) + (2 x^3 +3 x)

adding x^3 terms, now we get

`(7+2)x^3-4 x^2+3 x`

`9 x^(3) - 4 x^2 +3 x`

Therefore the sum of given polynomial is

`9 x^3-4 x^2+3 x`
