Question 214677
Is the expression {{{8/(w-1)}}} or is it {{{8/w-1}}} ???




{{{8/(w-1)}}} is undefined when the denominator {{{w-1}}} is zero. So set the denominator equal to zero and solve for 'w' to get {{{w-1=0}}} ----> {{{w=1}}}



So {{{8/(w-1)}}} is undefined when {{{w=1}}}



--------------------------------



{{{8/w-1}}} is undefined when the denominator {{{w}}} is zero. So set the denominator equal to zero to get {{{w=0}}}



So {{{8/w-1}}} is undefined when {{{w=0}}}
