Question

Find the roots

r = \frac{1}{2}

Alternative Form

r = 0.5

Evaluate

(2 r - 1)

To find the roots of the expression,set the expression equal to 0

2 r - 1 = 0

Move the constant to the right-hand side and change its sign

2 r = 0 + 1

Removing 0 doesn't change the value,so remove it from the expression

2 r = 1

Divide both sides

\frac{2 r}{2} = \frac{1}{2}

Solution

r = \frac{1}{2}

Alternative Form

r = 0.5
