Explain the steps involved in adding two rational expressions.

Answer:

To add two rational expressions, first factor each denominator completely to find the least common denominator (LCD). Next, rewrite each expression so that it has the LCD by multiplying the numerator and denominator by the missing factors. Then, add the resulting numerators together while keeping the common denominator. Finally, simplify the expression by factoring the numerator and canceling any common factors with the denominator.
