Question from a student: I have a question that continues to lead me to the answer x/(x - 1) but according to my math book, the answer should be 1/(x - 1). Who is right? Who is wrong? Here is the question: (x^2 - 6x - 27)/(x^2 - 11x + 18) DIVIDED by (x^3 + 2x^2 - 3x)/(x^2 - 2x) |
Hi there.
First, I factored the polynomials. Then I multiplied by the reciprocal of the denominator instead of dividing by the fraction. The book is right.
Hope this helps,
Stephen La Rocque.
