Evaluate

k - 11 k

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

(1 - 11) k

Subtract the numbers

- 10 k

- 10 k - 12

Solution

- 2 (5 k + 6)

Show Solution

k = - \frac{6}{5}

Alternative Form

k = - 1.2

Evaluate

k - 11 k - 12

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

k - 11 k - 12 = 0

Subtract the terms

More Steps

Simplify

k - 11 k

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

(1 - 11) k

Subtract the numbers

- 10 k

- 10 k - 12 = 0

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

- 10 k = 0 + 12

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

- 10 k = 12

Change the signs on both sides of the equation

10 k = - 12

Divide both sides

\frac{10 k}{10} = \frac{- 12}{10}

Divide the numbers

k = \frac{- 12}{10}

Solution

More Steps

Evaluate

\frac{- 12}{10}

Cancel out the common factor 2

\frac{- 6}{5}

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

- \frac{6}{5}

k = - \frac{6}{5}

Alternative Form

k = - 1.2
