Which equation shows function g in factored form? g(x) = 2x^2 – 6x – 56

O A. g(x) = 2(x-4)(x + 7)

OB. g(x) = 2(x2-3x-28)

OC. g(x) = (2x + 7)(x-8)

OD. g(x) = 2(x + 4)(x - 7)

An arrow is shot vertically upward at a rate of 180ft/s. use the projectile formula h=−16t2+v0t to determine at what time(s), in seconds, the arrow is at a height of 420ft. round your answer(s) to the nearest tenth of a second.

How do you use the elimination method for this question? explain, because i really want to understand!
