4x^2 -4x +1=0 is the same thing that (2x-1)^2=0 so the result is x=1/2

You shouldn't use x=(-b+-squared b^2-4ac)/4a because b^2-4ac=0 so is easier and faster

x2 – 4x – 5 = 0 (x - 5) (x + a million) = 0 So x = +5 or x = -a million For the quadratice equation: a = a million, b = -4, c = -5 Sqrt b^2 - 4ac = sqrt (sixteen - (4 * a million * -5)) = sqrt (sixteen - (-20)) = sqrt (36) = +6 or -6 The quadratic equation is then: [- (-4) +/- 6 ]/ 2 = 2 +/- 3 = +5 or -a million

The equation is 4x^2 - 4x + 1 = 0

1) Factor the equation by FOIL

4x^2 - 4x + 1 = 0

(2x - 1)(2x - 1) = 0

2) Divide both sides of the equation by 2x - 1

2x - 1 = 0

3) Add both sides by 1

2x = 1

4) Divide both sides by 2

x = 1/2

the quadratic formula: negative b plus or minus the square root of B squared minus 4 AC all over 2a
