Question 197213: If f(x)= 3x^2 -27/ 18x + 30 and g(x) = x^2 -7x +12/ 3x^2 -7x -20 , find f(x) divided by g(x) for all values of x for which the expression is defined and express your answer in simplest form. Help is appreciated! Thank you!
Solution:
f(x)=------(1)
g(x) = ------(2)
f(x)/g(x)==> f(x)*(1/g(x))

-----
f(x) = [3(x-3)(x+3)]/[6(3x+5)]
---------------------------------
g(x) = [(x-3)(x-4)]/[3x^2 -12x + 5x - 20]
= [(x-3)(x-4)]/[(x-4)(3x+5)]
--------------------
Cancel the factors that are common to a numerator and a denominator to get:
f(x)/g(x) = [(x+3)/2/[1/1]
---
f(x)/g(x) = [(x+3)/[2]
