Question

Choose the correct sum of the polynomials
(4x^3 − 2x − 9) + (2x^3 + 5x + 3)


6x^3 − 3x − 6

2x^3 − 7x − 12

6x^3 + 3x − 6

2x^3 + 3x − 3

Answer 1

find the like terms

4x^3 + 2x^3 -2x + 5x -9 + 3

then you'll have the answer

Answer 2

what i got isnt givin me the answer

Answer 3

so you have (4 + 2)x^3 + (-2 + 5)x +(-9 + 3)

and the answer is one of your choices.
