Answer:
B.
Step-by-step explanation:
Move 100 to the left side and subtract from both sides. Then subtract 100 from 4. Factor x^2-4x-96 using the AC method.=0 x^2+bx+c. Find a product that is -96 and a sum -4. This will be -12, 8. The factored form is (x-12)(x+8)=0. Then, solve for x.
(x-12)=0 (x+8)=0. You get x=12, -8.
