basically you never want to multiply or divide by zero so the restriction is the value that would create that situation.

hope your visits were fine. the original is not clearly written. can you use the "draw" below and write it out ?

$\frac{ x - 7 }{ x + 4} \div \frac{ x }{ x +3 }$

4. anonymous

$\frac{ x-7 }{ x+4 }\times \frac{ x+3 }{ x }$ restrictions are$x+4\neq0,x \neq-4~and~x \neq0$
