complete the square

2 x^{2} - 8 x - 16

2 (x - 2)^{2} - 24

Solution steps

2 x^{2} - 8 x - 16

Write

2 x^{2} - 8 x - 16

in the form:

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

Factor out

2

2 (x^{2} - 4 x - 8)

2 a = - 4 : a = - 2

Add and subtract

(- 2)^{2}

2 (x^{2} - 4 x - 8 + (- 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} - 8 - (- 2)^{2})

Simplify

2 (x - 2)^{2} - 24

2 x^{2} + b x + 2 = 0

2 y^{2} - 8 = 6 - 2 y^{2}

x, \frac{x ^{2}}{18} = R

x, x^{2} y = 9

9 x^{2} - 30 x + 23 = 0
