complete the square

x^{2} - 26 x

(x - 13)^{2} - 169

Solution steps

x^{2} - 26 x

Write

x^{2} - 26 x

in the form:

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

2 a = - 26 : a = - 13

Add and subtract

(- 13)^{2}

x^{2} - 26 x + (- 13)^{2} - (- 13)^{2}

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

x^{2} - 26 x + (- 13)^{2} = (x - 13)^{2}

(x - 13)^{2} - (- 13)^{2}

Simplify

(x - 13)^{2} - 169

9 x^{2} - 18 x = - 3

- 8 = - x^{2} - 4

r^{2} + 2 r + 4 = 0

- 5 x^{2} - 9 x = x^{2} + 2 x - 8

x, x^{2} + 2 x + 2 = 0
