complete the square

x^{2} + 6 x - 5

(x + 3)^{2} - 14

Solution steps

x^{2} + 6 x - 5

Write

x^{2} + 6 x - 5

in the form:

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

2 a = 6 : a = 3

Add and subtract

3^{2}

x^{2} + 6 x - 5 + 3^{2} - 3^{2}

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

x^{2} + 6 x + 3^{2} = (x + 3)^{2}

(x + 3)^{2} - 5 - 3^{2}

Simplify

(x + 3)^{2} - 14

3 u^{2} + 27 u = 0

x^{2} + 6 x + 9 = 0

x, 9 x^{2} + 4 y^{2} + 36 x - 24 y + 72 = 0

x, 4 x^{2} - y^{2} + 2 z^{2} + 4 = 0

8 x^{2} + 12 x + 3 = 0
