Question

Find the roots

r = \frac{5}{4}

Alternative Form

r = 1.25

Evaluate

4 r - 5

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

4 r - 5 = 0

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

4 r = 0 + 5

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

4 r = 5

Divide both sides

\frac{4 r}{4} = \frac{5}{4}

Solution

r = \frac{5}{4}

Alternative Form

r = 1.25
