complete the square

x^{2} + 4 x - 12

(x + 2)^{2} - 16

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} - 16

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

18 x - 6 = 9 x^{2}

y, x^{2} y^{2} + x y = 12

x^{2} - 5 x - 12 = - 5 x + 4

3 x^{2} + 2 x + a x^{2} + 5 a + 1 = 0
