Set each factor equal to 0.
[tex]\twoheadrightarrow\sf 5x+7=0[/tex]
[tex]\twoheadrightarrow\sf 8x+7=0[/tex]
[tex]\bullet[/tex] Solve each equation
[tex]\twoheadrightarrow\sf 5x+7=0[/tex]
[tex]\bullet[/tex] Subtract 7 from both sides
[tex]\twoheadrightarrow\sf 5x=-7[/tex]
[tex]\bullet[/tex] Divide both sides by 5
[tex]\underline{\twoheadrightarrow\sf x=-\cfrac{7}{5}}[/tex]
[tex]\bullet[/tex] Now let's solve the second equation
[tex]\twoheadrightarrow\sf 8x+7=0[/tex]
[tex]\bullet[/tex] Subtract 7 from both sides
[tex]\twoheadrightarrow\sf 8x=-7[/tex]
[tex]\bullet[/tex] Divide both sides by 8
[tex]\underline{\twoheadrightarrow\sf x=-\cfrac{7}{8}}[/tex]
[tex]\bullet[/tex] Great job, we found the two possible values
