Let
(1)
(2)
(3)
(4)
Then we have
(4) ((1)/(2))*((4)/(3))
The first expression (1) factors into
(5)
and the second expression (2) factors into
(6)
Then (1)/(2) reduces to
(7) or
(8)
The third expression (3) does not factor and the fourth expression (4) factors into
(9) so that (4)/(3) is
(10)
Now carry out the operatios of (4) to get the answer
(11)
which reduces to
(12) a+b
Answer: a+b
