    I just need help canceling out the main fraction in limit

    How do I get rid of the "a-2" part of the equation?

    [1/a -1/2] / (a -2)
    Combine the two fractions in the numerator into one fraction only, where their common denominator is 2*a,
    = [(2 -a)/(2a)] / (a-2)
    = [-(a-2)/(2a)] / (a-2)
    = -1/(2a)

    what are your options? not many.

    simplify the fractions in the top, it will turn out that you will be able to cancel the a - 2 in the bottom
