Find the roots
b1=0,b2=21
Alternative Form
b1=0,b2=0.5
Evaluate
(2b×1)(2b−1)
To find the roots of the expression,set the expression equal to 0
(2b×1)(2b−1)=0
Multiply the terms
2b(2b−1)=0
Elimination the left coefficient
b(2b−1)=0
Separate the equation into 2 possible cases
b=02b−1=0
Solve the equation
More Steps

Evaluate
2b−1=0
Move the constant to the right-hand side and change its sign
2b=0+1
Removing 0 doesn't change the value,so remove it from the expression
2b=1
Divide both sides
22b=21
Divide the numbers
b=21
b=0b=21
Solution
b1=0,b2=21
Alternative Form
b1=0,b2=0.5
