What is the greatest common factor of the numerator and denominator of the rational expression below? 5x-20/x^2-2x-8
1 answer:
Factories both equations:
5(x - 4) / (x + 2)(x - 4)
Then take out the common brackets:
5 / x + 2
Minus 2 from both sides:
3 / x
If you are looking for the greatest common factor of the numerator and denominator, the answer would be (x - 4)
