Evaluate

f - 22 f - 35

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

f - 22 f - 35 = 0

Subtract the terms

More Steps

Simplify

f - 22 f

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

(1 - 22) f

Subtract the numbers

- 21 f

- 21 f - 35 = 0

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

- 21 f = 0 + 35

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

- 21 f = 35

Change the signs on both sides of the equation

21 f = - 35

Divide both sides

\frac{21 f}{21} = \frac{- 35}{21}

Divide the numbers

f = \frac{- 35}{21}

Solution

More Steps

Evaluate

\frac{- 35}{21}

Cancel out the common factor 7

\frac{- 5}{3}

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

- \frac{5}{3}

f = - \frac{5}{3}

Alternative Form

f = - 1. \dot{6}
