Homework Help: How i can derivative this problem

  1. Jun 6, 2010 #1
    Hi all

    Queation say : x^2 - 2x + 3 / X^5

    I try to solve

    y1 = X^2/X^5 - 2x/x^5 + 3 X^5

    If this derivative is coorect if yes how i can complet

    Use the product rule on (1/x^5) and (x^2-2x+3)

    Should end up with -2/x^5+2/x^4-(5 (x^2-2 x+3))/x^6

    If the function is y = (x^2 - 2x + 3)/x^5, then you can rewrite the equation as y = x^2/x^5 - 2x/x^5 + 3/x^5.

    Each term should be simplified. Then you can differentiate each term to get y'.
