Solve for x. x2 − x − 12 = 0 A) x = −2 or x = 6 B) x = 2 or x = −6 C) x = −4 or x = 3 Eliminate D) x = 4 or x = −3
Accepted Solution
A:
Answer:D) x = 4 or x = −3Step-by-step explanation:x^2 − x − 12 = 0FactorWhat 2 numbers multiply to -12 and add to -1-4*3 = -12-4+3 = -1(x-4) (x+3) =0Using the zero product propertyx-4 =0 x+3 =0x=4 x=-3
