(1 - 15) f

Subtract the numbers

- 14 f

- 14 f - 16

Solution

- 2 (7 f + 8)

Show Solution

f = - \frac{8}{7}

Alternative Form

f = - 1. \dot{1} 4285 \dot{7}

Evaluate

f - 15 f - 16

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

f - 15 f - 16 = 0

Subtract the terms

More Steps

Simplify

f - 15 f

Collect like terms by calculating the sum or difference of their coefficients

(1 - 15) f

Subtract the numbers

- 14 f

- 14 f - 16 = 0

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

- 14 f = 0 + 16

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

- 14 f = 16

Change the signs on both sides of the equation

14 f = - 16

Divide both sides

\frac{14 f}{14} = \frac{- 16}{14}

Divide the numbers

f = \frac{- 16}{14}

Solution

More Steps

Evaluate

\frac{- 16}{14}

Cancel out the common factor 2

\frac{- 8}{7}

Use \frac{- a}{b} = \frac{a}{- b} = - \frac{a}{b} to rewrite the fraction

- \frac{8}{7}

f = - \frac{8}{7}

Alternative Form

f = - 1. \dot{1} 4285 \dot{7}
