Evaluate

2 x - 22 x - 2

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

2 x - 22 x - 2 = 0

Subtract the terms

More Steps

Simplify

2 x - 22 x

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

(2 - 22) x

Subtract the numbers

- 20 x

- 20 x - 2 = 0

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

- 20 x = 0 + 2

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

- 20 x = 2

Change the signs on both sides of the equation

20 x = - 2

Divide both sides

\frac{20 x}{20} = \frac{- 2}{20}

Divide the numbers

x = \frac{- 2}{20}

Solution

More Steps

Evaluate

\frac{- 2}{20}

Cancel out the common factor 2

\frac{- 1}{10}

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

- \frac{1}{10}

x = - \frac{1}{10}

Alternative Form

x = - 0.1
