We have already seen how to enter some simple fractions.  Fractions with complicated numerators or denominators must have the numerator and/or denominator surrounded by brackets.  These brackets will not be displayed, they are used as logical brackets so that you clearly indicate the elements that comprise the numerator and denominator.

 

Examples:

fxe0151                        is entered as (3x+2)/4

fxe0150                is entered as ((x+1)2(x+2))/(x+1)

clip1715        is entered as x=(-b +- sr(b2-4ac))/2a  or you can use the qf standard shortcut.

 

 

fxe0127                is entered as 1/(1+4x^(3x/2)+1/(2x2+1/2))
