What is the difference of the rational expression below? 14x/17-3x/17 17x/17 11x/17 42x/17 42x/289

Solution

Denominators are the same

So, we can directly subtract numerators as below :

(14x - 3x) / 17

Now, what is 14 - 3? That,s right, it\'s 11

So, 14x - 3x is 11x, right?

So, the answer is :

11x/17
