Hi I am in need of help, please... The question says to perform the indicated operation.
x^2+2x-3/x^2-9 Divided By x^2-1/x^3-27
I put divided by in the middle to show that it is dividing two rational expressions.
x^2+2x-3/x^2-9 to (x+3)(x-1)/[(x+3)(x-3)]
Similarly factor what you can in the x^2-1/x^3-27
and you will get some more cancellations when you do the final division.
Hint: x^3-27 can be factored, and one of its factors is (x-3). I wil leave you to figure out the other one.
Ooo ok thanks so much, I got it :D
