complete the square

2 x^{2} - 8 x + 4

2 (x - 2)^{2} - 4

Solution steps

2 x^{2} - 8 x + 4

Write

2 x^{2} - 8 x + 4

in the form:

x^{2} + 2 a x + a^{2}

Factor out

2

2 (x^{2} - 4 x + 2)

2 a = - 4 : a = - 2

Add and subtract

(- 2)^{2}

2 (x^{2} - 4 x + 2 + (- 2)^{2} - (- 2)^{2})

x^{2} + 2 a x + a^{2} = (x + a)^{2}

x^{2} - 4 x + (- 2)^{2} = (x - 2)^{2}

2 ((x - 2)^{2} + 2 - (- 2)^{2})

Simplify

2 (x - 2)^{2} - 4

- \frac{1.85}{20.25} x^{2} + \frac{1.85}{20.25} x + 1.82716049

x, x^{2} - 4 x y + 5 y^{2} - 4 y + 4 = 0

x, F = 2 x y^{2} x + (y + 2 y x^{2}) y

184 = - 0.01 q^{2} + 200

64 x^{2} = 121
