b-\frac{1}{2}=0 b-\frac{1}{2}=0
Take the square root of both sides of the equation.
b-\frac{1}{2}-\left(-\frac{1}{2}\right)=-\left(-\frac{1}{2}\right) b-\frac{1}{2}-\left(-\frac{1}{2}\right)=-\left(-\frac{1}{2}\right)
Add \frac{1}{2} to both sides of the equation.
b=-\left(-\frac{1}{2}\right) b=-\left(-\frac{1}{2}\right)
Subtracting -\frac{1}{2} from itself leaves 0.
b=\frac{1}{2}
Subtract -\frac{1}{2} from 0.
