Answer

$x=0$ and $x=4$ and $x=\frac{9}{2}$

Work Step by Step

$5x(x-4)(2x-9)=0$ Using the Zero Product Property $5x=0$ and $x-4=0$ and $2x-9=0$ The first equation: $5x=0$ Divide by $5$ $x=0$ The second equation $x-4=0$ Add $4$ to both sides $x=4$ The third equation $2x-9=0$ Add $9$ to both sides $2x=9$ Divide by $2$ $x=\frac{9}{2}$
