Find the roots
x1=0,x2=1
Evaluate
(x2×2)(x−1)
To find the roots of the expression,set the expression equal to 0
(x2×2)(x−1)=0
Use the commutative property to reorder the terms
2x2(x−1)=0
Elimination the left coefficient
x2(x−1)=0
Separate the equation into 2 possible cases
x2=0x−1=0
The only way a power can be 0 is when the base equals 0
x=0x−1=0
Solve the equation
More Steps

Evaluate
x−1=0
Move the constant to the right-hand side and change its sign
x=0+1
Removing 0 doesn't change the value,so remove it from the expression
x=1
x=0x=1
Solution
x1=0,x2=1
