17. Solve the equation 2x2 + 2x + 12 = 3x2 - X + 2.
A. X = 2, X = 5
B. X = -5, X =-2
C. X = -2, X = 5
D. X = 2, X = -5

B. X = -5, X =-2
Assuming the equation is
2x^2 + 2x + 12 = 3x^2 - X + 2 , and the big X is the same as little x
x^2 - 3x - 10 = 0
(x + 2)(x - 5) = 0
x = -2, x = 5
The bot was close, but wrong, and since it didn't show any steps
would get a zero.
