Explain the steps involved in adding two rational expressions.

Answer:

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