rational expression x^38 / 3x^2x  10 
Re: rational expression Hello, lalex0710! Quote:
A wild guess . . . you want this simplified? Do you know anything about Factoring? 
Re: rational expression Yes, I do know how to factor, but I am unfamiliar with exponents higher than power of 2. Anyways, thanks for the answer, and I have one more question lol. x^24 / x^3+4x^24x16 
Re: rational expression For the previous question, could you also elaborate on the answer. I don't quite understand how you pulled out the (x2) as common factor, and factored the rest. 
Re: rational expression Hi lalex0710, For the second problem, , here is how I would work it: First, find the x values of the zeroes of the numerator and plug then into the denominator to see which ones result in 0. You then can divide through by that term (or terms) using long division to factor. is 0 at so and are factors. The denominator at is and at the denominator is So both and divide the denominator. Therefore divides the denominator. Use long division to factor out giving: Note that this is also Also note that at , the denominator is as expected. Finally, check all calculations by picking (not a zero, and I like to use a number not likely to coincidentally give an equality): Carrying this back to the first problem, note that at so is a factor. At the denominator is so is a factor of the denominator as well. Long division may be used to find the results presented. Finally, there are no real roots of so the expression cannot be simplified any further.
