Let's solve your equation step-by-step.
(x−18)2=1
Step 1: Simplify both sides of the equation.
x2−36x+324=1
Step 2: Subtract 1 from both sides.
x2−36x+324−1=1−1
x2−36x+323=0
Step 3: Factor left side of equation.
(x−17)(x−19)=0
Step 4: Set factors equal to 0.
x−17=0 or x−19=0
x=17 or x=19
Answer:
x=17 or x=19
