Q. Simplify. Express your answer as a single fraction in simplest form. rs2−3r3s5
Find Common Denominator: Identify the common denominator for the fractions.Since the fractions have different denominators, we need to find a common denominator to combine them. The denominators are rs and 3. The least common denominator (LCD) is 3rs.
Rewrite Fractions: Rewrite each fraction with the common denominator.We will multiply the numerator and denominator of the first fraction by 3 to get the common denominator of 3rs.rs2×33=3rs6For the second fraction, we will multiply the numerator and denominator by 1, as it already has the common denominator.3r3s5×11=3rsr3s5
Combine Fractions: Combine the fractions.Now that both fractions have the common denominator of 3rs, we can combine them.(6−r3s5)/3rs
Simplify Expression: Simplify the expression if possible.In this case, there are no like terms in the numerator, and the expression is already in its simplest form.Final expression: (6−r3s5)/3rs
