Show Solution

u = - \frac{5}{4}

Alternative Form

u = - 1.25

Evaluate

u - 17 u - 20

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

u - 17 u - 20 = 0

Subtract the terms

More Steps

Simplify

u - 17 u

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

(1 - 17) u

Subtract the numbers

- 16 u

- 16 u - 20 = 0

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

- 16 u = 0 + 20

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

- 16 u = 20

Change the signs on both sides of the equation

16 u = - 20

Divide both sides

\frac{16 u}{16} = \frac{- 20}{16}

Divide the numbers

u = \frac{- 20}{16}

Solution

More Steps

Evaluate

\frac{- 20}{16}

Cancel out the common factor 4

\frac{- 5}{4}

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

- \frac{5}{4}

u = - \frac{5}{4}

Alternative Form

u = - 1.25
