Course

#### Question

Find the roots of the following quadratic equations, if they exist, by the method of completing the square 4x^2 + 4sqrt3x + 3 = 0

#### Solution

4x^2 + 4sqrt3x + 3 = 0

⇒ (2x)^2 + 2 × 2x × sqrt3 + (sqrt3)2 = 0

⇒ (2x + sqrt3)^2 = 0

⇒ (2x + sqrt3) = 0

⇒ x = (-sqrt3)/2

Is there an error in this question or solution?
