Answer

$x=-5$ and $x=\frac{3}{8}$

Work Step by Step

$3(x+5)(8x-3)=0$ Using the Zero Product Property $3=0$ and $x+5=0$ and $8x-3=0$ The first equation $3=0$ is false and cannot be solved. The second equation: $x+5=0$ subtract $5$ from both sides $x=-5$ The third equation $8x-3=0$ add $3$ to both sides $8x=3$ Divide by $8$ $x=\frac{3}{8}$
