Answer:
Option (b) is correct.
Step-by-step explanation:
Given: Polynomial [tex]2x^3-5x-1[/tex] and [tex]4x^3+8x+3[/tex]
We have to find the sum of given polynomial and choose the correct option from given options.
Consider the given Polynomial [tex]2x^3-5x-1[/tex] and [tex]4x^3+8x+3[/tex]
We have to find the sum that is [tex]2x^3-5x-1+(4x^3+8x+3)[/tex]
Apply plus minus rule [tex]+(-a)=-a[/tex]
We have,
[tex]2x^3-5x-1+4x^3+8x+3[/tex]
Now adding like terms, we have,
Like terms are terms having same variable with same degree.
[tex](4+2)x^3+(8-5)x-1+3[/tex]
Simplify , we have,
[tex]6x^3+3x+2[/tex]
Thus, option (b) is correct.
