Hi!

\rightsquigarrow\circ\boldsymbol{Explanation}\circ\leftharpoonup

Set each factor equal to 0.

\twoheadrightarrow\sf 5x+7=0

\twoheadrightarrow\sf 8x+7=0

\bullet <em>Solve each equation</em>

\twoheadrightarrow\sf 5x+7=0

\bullet <em>Subtract 7 from both sides</em>

\twoheadrightarrow\sf 5x=-7

\bullet <em>Divide both sides by 5</em>

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

\bullet <em>Now let's solve the second equation</em>

\twoheadrightarrow\sf 8x+7=0

\bullet <em>Subtract 7 from both sides</em>

\twoheadrightarrow\sf 8x=-7

\bullet <em>Divide both sides by 8</em>

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

\bullet <em>Great job, we found the two possible values</em>

(5x + 7)(8x + 7) \\  \\ 5x + 7 = 0 \\  \\ 5x =  - 7 \\  \\ x =  \frac{ - 7}{5}  \\  \\ 8x + 7 = 0 \\  \\ 8x =  - 7 \\  \\ x =  \frac{ - 7}{8} .

the values of x are -7/5 and -7/8 .
