Since \"(x-1)^1/2-x(1/2)(x-1)^-1/2/x-1\" is very ambiguous, you will need to repost your question using parentheses:
  • Around each numerator
  • Around each denominator
  • Around each exponent
  • Around each expression to which an exponent applies. (Note that \"expression\" is italicized. If an exponent applies to just a variable, you do not need to put parentheses around the variable.)

\n" ); document.write( "Without these parenthese there are just too many ways to interpret \"(x-1)^1/2-x(1/2)(x-1)^-1/2/x-1\". Taken literally, \"(x-1)^1/2-x(1/2)(x-1)^-1/2/x-1\" means:
\n" ); document.write( "\"%28x-1%29%5E1%2F2-x%281%2F2%29%28x-1%29%5E-1%2F2%2Fx-1\" which is probably not what you meant. \n" ); document.write( "
