With this one, I know i need to add up the nominator and denominator by finding a common denominator for each..then to take:
[(t^2-s^2)/(s^(2)t^(2))]/[(t+s)/(st)]
But then I'm stuck.
Please and thanks!!
#1)What are you supposed to do here?
#2) Factor. You should get
and you get some nice cancellation.
#3)Multiply the whole thing by (st)/(st)
Or notice you can apply the difference of squares formula to the numerator and notice that something cancels ;):
Much more elegant.Quote:
