Answer the question.Explain the difference between adding rational expressions and solving rational equations.
What will be an ideal response?
When adding rational expressions, we use the least common denominator to write an expression equivalent to the sum of the given expressions. We do not clear fractions when adding rational expressions. When solving rational equations, we use the least common denominator to clear fractions and then proceed to find the value(s) of the variable for which the equation is true.
