complete the square

2 x^{2} - 10 x + 8

2 (x - \frac{5}{2})^{2} - \frac{9}{2}

Solution steps

2 x^{2} - 10 x + 8

Write

2 x^{2} - 10 x + 8

in the form:

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

Factor out

2

2 (x^{2} - 5 x + 4)

2 a = - 5 : a = - \frac{5}{2}

Add and subtract

(- \frac{5}{2})^{2}

2 (x^{2} - 5 x + 4 + (- \frac{5}{2})^{2} - (- \frac{5}{2})^{2})

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

x^{2} - 5 x + (- \frac{5}{2})^{2} = (x - \frac{5}{2})^{2}

2 ((x - \frac{5}{2})^{2} + 4 - (- \frac{5}{2})^{2})

Simplify

2 (x - \frac{5}{2})^{2} - \frac{9}{2}

2 x^{2} - 10 x + 3

x^{2} + (- \frac{1}{6})^{2} = 1^{2}

(X + 2) (X - 3) + 2 (3 X - 4) = 3 X + 1

x^{2} + (\frac{90}{2000}) x + (\frac{1500}{2000}) = 0

x^{2} + (x - 7)^{2} = 132
