Question

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

Answer 1

Answer:

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}
