Solution
Solution Steps
To convert the given quadratic equation x2−6x+1=0 into the form (x−p)2=q, we need to complete the square.
Start with the quadratic equation x2−6x+1=0.
Move the constant term to the other side: x2−6x=−1.
Add and subtract the square of half the coefficient of x (which is −6/2=−3) inside the equation: x2−6x+9=−1+9.
Simplify the equation to get it in the form (x−p)2=q.
Step 1: Start with the given quadratic equation
The given quadratic equation is:
x2−6x+1=0
Step 2: Move the constant term to the other side
Rearrange the equation by moving the constant term to the right side:
x2−6x=−1
Step 3: Complete the square
To complete the square, add and subtract the square of half the coefficient of x (which is −6/2=−3):
x2−6x+9=−1+9(x−3)2=8
Step 4: Verify the equivalent form
The equivalent form of the given quadratic equation is:
(x−3)2=8
