    Reduce each rational expression to lowest terms. Assume that the variables represent only numbers for which the denominators are nonzero 6.1 34, 78,88

    a^2-b^2
    a-b = (a-b)(a+b) / (a-b) = a+b

    Reduce to lowest terms

    4x^2
    2x^9
    = 2 x^2 / x^9 = 2/x^7

    -2x-8
    x^2+2x-8 we will factor both top and bottom and get:

    = -2(x+4) / (x+4)(x-2) = -2 / x-2 , after simplifying by x+4.

    perform indicted operation 6.2 22,68,74

    3 * 2a+2
    a^2+a 6

    = 3*2(a+1) / a(a+1)*6 = 1/a , after simplifying by 6 and a+1

    -2a^2 *20a
    3a^2 15a^3

    = -40 a^3 / 45 a^5 = -8/9a^2 , after simplifying by 5 and a^3

    w^2-1 * w-1
    (w-1)^2 w^2+2w+1

    = ...

    Solution Summary

    The expert reduces the rational expression to the lowest terms of denominators.
