Answer 8

You would make equal denominators. Since the second fraction needs a b in the denominator, you would multiply its numerator and denominator by b. You would get:
1 b^2
-- + ---
2b 2b

Then you can just add the numerators to get the sum of both fractions.
1 + b^2 = ?

Answer 9

so it would be B^2+1
------
2b
