complete the square

x^{2} - 2 x - 4

(x - 1)^{2} - 5

Solution steps

x^{2} - 2 x - 4

Write

x^{2} - 2 x - 4

in the form:

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

2 a = - 2 : a = - 1

Add and subtract

(- 1)^{2}

x^{2} - 2 x - 4 + (- 1)^{2} - (- 1)^{2}

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

x^{2} - 2 x + (- 1)^{2} = (x - 1)^{2}

(x - 1)^{2} - 4 - (- 1)^{2}

Simplify

(x - 1)^{2} - 5

x^{2} - 2 x - 2

x^{2} - 2 x + 3

u^{2} - 4 = 0

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

4 x^{2} = - 6 x
