Question 472121: I am trying to add a rational expression with an unlike denominator.
Simplify the expression: 3/x + 2/x^2
I do not understand from my math book how to find the least common denominator in order to rewrite the fractions using the least common denominator.
So far I am at:
3/x + 2/x*x
I understand that the least common denominator contains the highest power of each factor that appears in either denominator. So does that mean that the least common denominator is x from both denominators giving you x^2?
If that is so, I come up with: 3x/x^2 + 2/x^2
If I combine these two I have (3x + 2)/x^2
Is this thinking process correct?
