What is the sum of the rational expressions below?<br> 3x-1/2x + 3x/x-1
Elden [556K]
In order to find the sum of the given rational expressions above, here are the steps.
Firstly, you need to find the LCM of the least common denominator.
So it would look like this: 
<span>3x-1 +   3x            (3x-1)(x-1) + (2x)(3x)
------    -------    =    ---------------------------
  2x       x-1                  2x(x-1)

3x^2-4x+1+6x^2
----------------------
    2x(x-1)
And the final result would be this:
9x^2-4x+1
--------------
  2x(x-1)

</span>9x^2-4x+1
--------------
  2x^2-2x
<span>
Hope that this is the answer that you are looking for.
