Question 150344


{{{(6)/(2n+4)}}} Start with the given expression



{{{2n+4=0}}} Set the denominator equal to zero. Remember, dividing by 0 is undefined.



{{{2n=0-4}}}Subtract 4 from both sides



{{{2n=-4}}} Combine like terms on the right side



{{{n=(-4)/(2)}}} Divide both sides by 2 to isolate n




{{{n=-2}}} Divide



So if {{{n=-2}}}, then the expression {{{(6)/(2n+4)}}} is undefined.
