Solve the equation 3x2 + 6x - 2 = 0
...Solve the equation 3x2 + 6x - 2 = 0
x = -1 ± √33
x = -1 ± √153
x = -2 ± 2
x = 3 ± √315
Correct answer is B
3x2 + 6x - 2 = 0
Using almighty formula i.e. x = b±√b2−4ac2a
a = 3, b = 6, c = -2
x = −6±√62−4(3)(−2)2(3)
x = −6±√36+246
x = −6±√606
x = −6±√4×156
x = −1±√153
