Question 945194
Same as the fraction skills you already learned.


{{{4/x+(3/(1/x))(x/x)+3}}}


{{{4/x+3x/1+3}}}


{{{highlight_green(4/x+3x+3)}}}


{{{4/x+3x(x/x)+3(x/x)}}}


{{{4/x+3x^2/x+3x/x}}}


{{{highlight((4+3x^2+3x)/x)}}}, but this may not be what you really want because it is a single rational expression, instead of partial sums.  You might really want the earlier green-outlined expression.
