and also
first expand all the terms which are the difference of two squares, and factorise of the denominator of the middle term:Originally Posted by Chuck_3000
Now cancell the common terms where possible:
Multiply the two denominators, and do any remaining cancellations:

First get rid of the division and replace it with a multiplication:Originally Posted by Chuck_3000
Now on the right hand side of the equals sign expand the difference of two
squares in the numerator of the first term and factorise the denominator of
the second term:
Now cancel where we can:
Now a little trial and error shows that is a factor of , so doing the
long division, and factoring out the factor of in the numerator of the last term gives:
Finally cancelling:
