complete the square

- 2 x^{2} - 4 x + 0

- 2 (x + 1)^{2} + 2

Solution steps

- 2 x^{2} - 4 x + 0

Write in the standard form

a x^{2} + b x + c

- 2 x^{2} - 4 x

Write

- 2 x^{2} - 4 x

in the form:

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

Factor out

- 2

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

2 a = 2 : a = 1

Add and subtract

1^{2}

- 2 (x^{2} + 2 x + 1^{2} - 1^{2})

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

x^{2} + 2 x + 1^{2} = (x + 1)^{2}

- 2 ((x + 1)^{2} - 1^{2})

Simplify

- 2 (x + 1)^{2} + 2

3 x^{2} - 32 = 0

- 53 = 1 - 6 n^{2}

x^{2} - 13 x = 90

6 x^{2} + 5 x - 10 = 0

- 11 + 6 x^{2} - 4 x^{2} = 0
