Final answer:
To find the quotient of the given rational expressions, multiply the first expression by the reciprocal of the second expression.
Step-by-step explanation:
To find the quotient of the given rational expressions, we need to multiply the first expression by the reciprocal of the second expression. The reciprocal of a rational expression is found by flipping the numerator and denominator. So, the reciprocal of x^2-9/3x-12 is 3x-12/x^2-9.
Now, we can multiply the two expressions x^2+5x+6/x-6 and 3x-12/x^2-9. Multiplying the numerators together and denominators together gives:
(x^2+5x+6)(3x-12) / (x-6)(x^2-9)
Then, simplify the expression if possible.
