11-60.

Solve each equation below for x.

1. $1234x + 23456 = 987654$

$x\approx781.36$

1. $\frac { 10 } { x } + \frac { 20 } { x } = 5$

Multiply both sides of the equation by $x$.

1. $5x^2 − 6x + 1 = 0$

Factor and use the Zero Product Property.

1. $x^3- 3x^2 + 2x = 0$

$x$ is a common factor. How many solutions do you expect from a cubic equation?
