Evaluate

x \times 2 - 11 x - 80

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

x \times 2 - 11 x - 80 = 0

Use the commutative property to reorder the terms

2 x - 11 x - 80 = 0

Subtract the terms

More Steps

- 9 x - 80 = 0

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

- 9 x = 0 + 80

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

- 9 x = 80

Change the signs on both sides of the equation

9 x = - 80

Divide both sides

\frac{9 x}{9} = \frac{- 80}{9}

Divide the numbers

x = \frac{- 80}{9}

Solution

x = - \frac{80}{9}

Alternative Form

x = - 8. \dot{8}
