Ineed to find the least common denominator of x+2/x^2+2x-3 , x-7/x^2+5x+6

(x + 3)(x - 1)(x + 2)  

Step-by-step explanation:

The fractions are:  

Factor each denominator  

We must find the least common multiple of the denominators.  We take the maximum power of each separate factor.

      Factors of first fraction = (x + 3) × (x - 1)

Factors of second fraction = (x + 3)             × (x + 2)

                                   LCM = (x + 3)(x - 1)(x + 2)

The lowest common denominator of the two fractions is (x + 3)(x - 1) (x + 2).
