Solve (x-1)(x 9)=8x

Evaluate

(x - 1) (x \times 9) = 8 x

Remove the parentheses

(x - 1) x \times 9 = 8 x

Multiply the terms

More Steps

9 x (x - 1) = 8 x

Expand the expression

More Steps

9 x^{2} - 9 x = 8 x

Move the expression to the left side

9 x^{2} - 17 x = 0

Factor the expression

More Steps

x (9 x - 17) = 0

When the product of factors equals 0,at least one factor is 0

9 x - 17 = 0 x = 0

Solve the equation for x

More Steps

x = \frac{17}{9} x = 0

Solution

x_{1} = 0, x_{2} = \frac{17}{9}

Alternative Form

x_{1} = 0, x_{2} = 1. \dot{8}
