Factor the following polynomial completely. 10x^4+ 80x^3 + 1120x^2 a. -10x^2(x+2)(x+6) b. 10x^2 (x+2)(x+6) c. -10x^2(x-2)(x+6) d. 10x^2 (x+2)(x+6)

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

d is the final answer!
