Question 74837
Set each factor equal to zero to solve for x
{{{x+5=0}}}
{{{x=-5}}} There's one answer
{{{x+7=0}}}
{{{x=-7}}} There's another answer
So the solutions are x=-5 or x=-7
<p>
Check:
{{{(-5+5)(x+7)=0 }}}Plug in x=-5
{{{(0)(x+7)=0 }}}
{{{0=0 }}}works
{{{(x+5)(-7+7)=0 }}}Plug in x=-7
{{{(x+5)(0)=0 }}}
{{{0=0 }}}works
