complete the square

x^{2} + 4 x + 12

(x + 2)^{2} + 8

Solution steps

x^{2} + 4 x + 12

Write

x^{2} + 4 x + 12

in the form:

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

2 a = 4 : a = 2

Add and subtract

2^{2}

x^{2} + 4 x + 12 + 2^{2} - 2^{2}

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

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

(x + 2)^{2} + 12 - 2^{2}

Simplify

(x + 2)^{2} + 8

z^{2} - 0.3063 z + 0.4317 = 0

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

c^{2} + c = 2

(3 - X)^{2} + X^{2} = 2 (5 - X)

8 x^{2} - 20 = 0
