Two fractions havedenominators of x^2+ 6x + 9and x^2. What is the LeastCommon Denominator?

The least common denominator (LCD) is the smallest number that can be a common denominator for a set of fractions. It's also known as the lowest common denominator.

The denominators of two fractions are given as:

Factoring the first expression:

It's clear there is no common factor between both denominators. Such expressions and numbers are called to be coprime.

For example, 9 and 25 are coprime, but they are not prime numbers individually.

When two numbers or expressions are coprime, the LCD is just their product.

Therefore the Least Common Denominator is:
