Question

Factor the following polynomial completely.

Answer 1

Answer:

10x^2 (x+2) (x+6)

Step-by-step explanation:

assuming you meant 120 not 1120

10x^4+ 80x^3 + 120x^2

factor out 10 x^2

10x^2 (x^2 +8x+12)

what numbers multiply together to get 12 and add together to get 8

2*6 = 12   2+6 = 8

10x^2 (x+2) (x+6)

B and D are the same answer?????
