a^2 b^2

------------------------- LCM=a^2b^2 If I multiply numerator >>> 2a^2 2a^2 2b^2 2b^2

3 3 ------ - ------ + ------- - -------

--- + ------ a^2 b^2 a^2 b^2

a^2 b^2

Is this correct at this point or did I improperly distribute?

Answer 1

If you multiply the "top" and "bottom" by a²b², you will get:

(2b² - 2a²) / (3b² + 3a²)

Answer 2

Cancel a^2*b^2=(2-2)/(3+3)=0
