complete the square

2 x^{2} + 16 x + 26

2 (x + 4)^{2} - 6

Solution steps

2 x^{2} + 16 x + 26

Write

2 x^{2} + 16 x + 26

in the form:

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

Factor out

2

2 (x^{2} + 8 x + 13)

2 a = 8 : a = 4

Add and subtract

4^{2}

2 (x^{2} + 8 x + 13 + 4^{2} - 4^{2})

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

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

2 ((x + 4)^{2} + 13 - 4^{2})

Simplify

2 (x + 4)^{2} - 6

x, 2 x^{2} - 7 x + 3 = 0

4 x^{2} + 268 = - 72 x

x^{2} + 7 x + 10 = 0

48 x + 12 x^{2} = 0

x, - 8 x^{2} + 5 x y + y^{3} = - 149
