i think in place of +2 its -2
Solving x2-12x-2 = 0 by the Quadratic Formula .
According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by :
- B ± √ B2-4AC
x = ————————
2A
In our case, A = 1
B = -12
C = -2
Accordingly, B2 - 4AC =
144 - (-8) =
152
Applying the quadratic formula :
12 ± √ 152
x = ——————
