What is the least common denominator (LCD) of \(x-3\), \(x+3\), and [tex]x^2-9[/tex]?
Answer (2)
The least common denominator is one, since all of these numbers are actually whole numbers. They're actually all 1 x − 3 1 x + 3 1 x 2 − 9 If you mean the greatest common factor, then it's obviously x
The least common denominator (LCD) of the expressions x − 3 , x + 3 , and x 2 − 9 is x 2 − 9 . This is because x 2 − 9 factors to ( x − 3 ) ( x + 3 ) , which includes both of the other expressions. Therefore, the LCD includes all unique factors.
