completesquare x^2-6x-1

Solution

complete the square

x^{2} - 6 x - 1

Solution

(x - 3)^{2} - 10

Solution steps

x^{2} - 6 x - 1

Write

x^{2} - 6 x - 1

in the form:

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

2 a = - 6 : a = - 3

Add and subtract

(- 3)^{2}

x^{2} - 6 x - 1 + (- 3)^{2} - (- 3)^{2}

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

x^{2} - 6 x + (- 3)^{2} = (x - 3)^{2}

(x - 3)^{2} - 1 - (- 3)^{2}

Simplify

(x - 3)^{2} - 10
