hello to all.
this happens to be a surd but could equally apply to any algebraic equation involving fractions.
ive been asked to solve the following in the form , where A, B and C are rational numbers.
my question is given any algebraic fraction should you always begin by multiplying the denominator?
because i get two answers depending on which way i go but only one is in the requested format, and thats the one that multiplies the denominator to start with, eg:
the other way give the correct answer if checked on a calculator but is not in the correct format
you could rationlize this surd which then give the same answer as above but this seems a bit long winded.
