complete the square

x^{2} + 4 x - 5

(x + 2)^{2} - 9

Solution steps

x^{2} + 4 x - 5

Write

x^{2} + 4 x - 5

in the form:

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

2 a = 4 : a = 2

Add and subtract

2^{2}

x^{2} + 4 x - 5 + 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} - 5 - 2^{2}

Simplify

(x + 2)^{2} - 9

x, x^{2} + 3 y^{2} - 4 x + 24 y + 52 = 0

s^{2} + 4 s + 1 = 0

3 x^{2} - 27 = - 6 x

2 x^{2} + 4 x - 11

10 x^{2} - 7 x - 1 = 0
