Question 244652: find the least common denominator x-3/x^2-4x-5 minus x-4/x^2-1

The factors of the first denominator are (x - 5)(x + 1), and the factors of the second denominator are (x + 1)(x - 1). So you have one factor of (x + 5), one factor (in each denominator) of (x + 1), and one factor of (x - 1). So the LCD is the product of those three factors.
