4-129.

Solve each equation.

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?
