complete the square

4 x^{2} + 8 x

4 (x + 1)^{2} - 4

Solution steps

4 x^{2} + 8 x

Write

4 x^{2} + 8 x

in the form:

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

Factor out

4

4 (x^{2} + 2 x)

2 a = 2 : a = 1

Add and subtract

1^{2}

4 (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}

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

Simplify

4 (x + 1)^{2} - 4

0 = 3 x^{2} - 27

4 x^{2} + 6 x

2 (t - 3)^{2} - 72 = 0

4.5 x = (2 x - 1)^{2}

5 x^{2} - 10 x - 255 = 0
