Find the roots
x1=0,x2=21
Alternative Form
x1=0,x2=0.5
Evaluate
(2x×1)(2x−1)
To find the roots of the expression,set the expression equal to 0
(2x×1)(2x−1)=0
Multiply the terms
2x(2x−1)=0
Elimination the left coefficient
x(2x−1)=0
Separate the equation into 2 possible cases
x=02x−1=0
Solve the equation
More Steps

Evaluate
2x−1=0
Move the constant to the right-hand side and change its sign
2x=0+1
Removing 0 doesn't change the value,so remove it from the expression
2x=1
Divide both sides
22x=21
Divide the numbers
x=21
x=0x=21
Solution
x1=0,x2=21
Alternative Form
x1=0,x2=0.5
