Answer:

Option (b) is correct.

Step-by-step explanation:

Given: Polynomial 2x^3-5x-1 and 4x^3+8x+3

We have to find the sum of given polynomial and choose the correct option from given options.

Consider the given Polynomial 2x^3-5x-1 and 4x^3+8x+3

We have to find the sum that is 2x^3-5x-1+(4x^3+8x+3)

Apply plus minus rule +(-a)=-a

We have,

2x^3-5x-1+4x^3+8x+3

Now adding like terms, we have,

Like terms are terms having same variable with same degree.

(4+2)x^3+(8-5)x-1+3

Simplify , we have,

6x^3+3x+2

Thus, option (b) is correct.
