Enter the correct answer in the box. Solve the quadratic equation by completing the square.

2x2 + 12x = 66

Fill in the values of a and b to complete the solutions.

X=a-sqrt b

X=a+sqrt b

Interpreting as: X=a-sqrt b X=a+sqrt b

Input:

X = a - sqrt (b) X = a + sqrt (b)

Alternate forms:

{a = (sqrt (b) + 1) X, a = X - sqrt (b), b = 0 ∨ X = - 1}

{a = (sqrt (b) + 1) X, a + sqrt (b) = X, sqrt (b) (X + 1) = 0}
