Question

Simplify the problem

Answer 1

The correct answer is D

`=4x^4-3x^3+3x^2 -3x+1`

Explanation:

The given polynomial is,

`(x^4+2x^2-5x)+(-3x^3+x^2+1)+(3x^4+2x)`

In order to simplify this polynomial, we must group like terms to obtain,

`=x^4+3x^4-3x^3 +2x^2 +x^2 -5x+2x+1`

Simplify to get,

`=4x^4-3x^3+3x^2 -3x+1`

Therefore the correct option is D.
