Find the roots
x1=0,x2=2
Evaluate
(x−2)(x2)(x−2)(x−2)
To find the roots of the expression,set the expression equal to 0
(x−2)(x2)(x−2)(x−2)=0
Calculate
(x−2)x2(x−2)(x−2)=0
Multiply

Multiply the terms
(x−2)x2(x−2)(x−2)
Multiply the terms with the same base by adding their exponents
(x−2)1+1+1x2
Add the numbers
(x−2)3x2
Use the commutative property to reorder the terms
x2(x−2)3
x2(x−2)3=0
Separate the equation into 2 possible cases
x2=0(x−2)3=0
The only way a power can be 0 is when the base equals 0
x=0(x−2)3=0
Solve the equation
More Steps

Evaluate
(x−2)3=0
The only way a power can be 0 is when the base equals 0
x−2=0
Move the constant to the right-hand side and change its sign
x=0+2
Removing 0 doesn't change the value,so remove it from the expression
x=2
x=0x=2
Solution
x1=0,x2=2
