Question

Which of the following is a factor of 2x4 + 22x3 + 60x2?

2x3

x4

x + 4

x + 5

Answer 1

the correct answer is x+5 :DDD it was also the correct answer on the test !

Answer 2

For the answer to the question above,
2x^4 + 22x^3 + 60x^2

GCF: 2x^2

2x^2(x^2 + 11x + 30) =
So the following factor for the problem above is
2x^2(x + 6)(x + 5)

If you want to double check, just multiply the answer.
I hope my answer helped you.
