What must be true of two rational expressions before they can be added?
VladimirAG [237]

Answer:

They most have common denominators.

Step-by-step explanation:

Let the following two rational expressions:

\frac{p}{a}  , \frac{q}{b}

where p,a,q, b are integers, a and b the denominators are not 0, i.e. a,b\neq 0

We can add rational expressions only if their denominator is same.

That is why we find LCD to be ab.

Then,

\frac{p}{a} +\frac{q}{b} =\frac{pb+qa}{ab}

Let the following two rational expressions:

\frac{p}{a}  , \frac{q}{b}

where p,a,q, b are integers, a and b the denominators are not 0, i.e. a,b\neq 0

We can add rational expressions only if their denominator is same.

That is why we find LCD to be ab.

Then,

\frac{p}{a} +\frac{q}{b} =\frac{pb+qa}{ab}

So, the correct answer is the last option that we can sum rational expressions if they have common denominator.
