Question

What is the sum of the polynomials (4x5+3x3−x−6)+(3x3−9x−4)

a/ 6x6+4x5−10x2−10
b/ 4x5+6x3−10x−10
c/ 4x5+6x3−8x+2
d/ 6x6+4x5−8x2+2
(please help!)

Answer 1

Its B I did the test and got it correct.

Answer 2

The given polynomials are

`image`

In this question we have to combine the like terms

`4x^5 + 3x^3 +3x^3 -x-9x-6-4`\

`=4x^5 +6x^3 -10x -10`

So out of the given options, correct option is b
