Question 152874
{{{W(x) = Q(x)-1}}} Start with the given equation.



{{{W(x) = (x+1)/(x-1)-1}}} Plug in {{{Q(x)=(x+1)/(x-1)}}}.



{{{W(x) = (x+1)/(x-1)-(x-1)/(x-1)}}} Multiply 1 by {{{(x-1)/(x-1)}}}



{{{W(x) = (x+1-(x-1))/(x-1)}}} Combine the fractions.



{{{W(x) = (x+1-x+1)/(x-1)}}} Distribute



{{{W(x) = (2)/(x-1)}}} Combine like terms



So the answer is C) {{{W(x) = (2)/(x-1)}}}
