complete the square

2 y^{2} + 8 y

2 (y + 2)^{2} - 8

Solution steps

2 y^{2} + 8 y

Write

2 y^{2} + 8 y

in the form:

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

Factor out

2

2 (y^{2} + 4 y)

2 a = 4 : a = 2

Add and subtract

2^{2}

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

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

y^{2} + 4 y + 2^{2} = (y + 2)^{2}

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

Simplify

2 (y + 2)^{2} - 8

15 x^{2} - 3 x = 0

25 p^{2} + 70 p + 49 = 0

- 0.2 x^{2} + 1.6 x

m^{2} = 4 m - 3

x^{2} + 2 x + c
