The equations that is the result of completing the square on x^2 - 6x - 9 = 0 is (x-3)^2 =18

Completing the square method

A quadratic equation is an equation that has a leading degrees of 2.

Given the equation below

x^2 - 6x - 9 = 0

Add 9 to both sides

x^2 - 6x - 9 + 9 = 9
x^2 - 6x = 9

Complete the square

x^2 - 6x + (-3)^2 = 9 + (-3)^2

(x-3)^2 = 9 + 9

(x-3)^2 =18

Hence the equations that is the result of completing the square on x^2 - 6x - 9 = 0 is (x-3)^2 =18
