1. Problem Description

We are given a quadratic equation to solve: x26x+9=0x^2 - 6x + 9 = 0. We need to find the value(s) of xx that satisfy this equation.

2. Solution Steps

We can solve this quadratic equation by factoring. We look for two numbers that multiply to 9 and add up to -

6. These numbers are -3 and -

3. Therefore, the quadratic equation can be factored as:

(x3)(x3)=0(x - 3)(x - 3) = 0
This can also be written as:
(x3)2=0(x - 3)^2 = 0
Taking the square root of both sides, we have:
x3=0x - 3 = 0
Adding 3 to both sides gives us:
x=3x = 3
Since both factors are the same, there is only one solution.

3. Final Answer

x=3x = 3
