Hi
4x^2-4x+3=0
Move the constant term to the right side of the equation
4x^2-4x=-3
Multiply each term in the equation by four times the coefficient of the x^2 term
64x^2 -64x = -48
Square the coefficient of the original x term and add it to both sides of the equation
64x^2 -64x + 16 = -48 + 16
Take the square root of both sides and complete as shown
(8x -4)^2 =(-32)
(8x -4) = ± sqrt(-32)
x = (4 ± sqrt(-32))8
