Solve f -2 -5f - 9

Evaluate

f - 2 - 5 f - 9

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

f - 2 - 5 f - 9 = 0

Subtract the terms

More Steps

- 4 f - 2 - 9 = 0

Subtract the numbers

- 4 f - 11 = 0

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

- 4 f = 0 + 11

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

- 4 f = 11

Change the signs on both sides of the equation

4 f = - 11

Divide both sides

\frac{4 f}{4} = \frac{- 11}{4}

Divide the numbers

f = \frac{- 11}{4}

Solution

f = - \frac{11}{4}

Alternative Form

f = - 2.75
