Explain the steps involved in adding two rational expressions.

Answer:

To add two rational expressions, first factor the denominators to find the least common denominator (LCD). Next, rewrite each expression so they both have the LCD by multiplying the numerator and denominator by any missing factors (multiplying by a form of one). Then, add the numerators together while keeping the denominator the same. Finally, factor the resulting numerator if possible and simplify the expression by dividing out common factors from the numerator and denominator.
