    Answer:

    √a(√a + 2)          a – 2√a

    —————– = —————–

        a – 4                a – 4

    Step-by-step explanation:

    I am assuming that by “sqrt(a)/sqrt(a)-2” you meant:

    √a

    ———-

    √a – 2

    To rationalize the denom., multiply numerator and denom. of this fraction by the conjugate of √a – 2, which is √a + 2:

    √a(√a + 2)

    —————–

        a – 4
