Set each factor equal to 0.

$\twoheadrightarrow\sf 5x+7=0$

$\twoheadrightarrow\sf 8x+7=0$

$\bullet$ Solve each equation

$\twoheadrightarrow\sf 5x+7=0$

$\bullet$ Subtract 7 from both sides

$\twoheadrightarrow\sf 5x=-7$

$\bullet$ Divide both sides by 5

$\underline{\twoheadrightarrow\sf x=-\cfrac{7}{5}}$

$\bullet$ Now let's solve the second equation

$\twoheadrightarrow\sf 8x+7=0$

$\bullet$ Subtract 7 from both sides

$\twoheadrightarrow\sf 8x=-7$

$\bullet$ Divide both sides by 8

$\underline{\twoheadrightarrow\sf x=-\cfrac{7}{8}}$

$\bullet$ Great job, we found the two possible values
