    Need Some help With expanding and simplifying.

    (expand and simplify)
    a. 3(2x-y)^2(x^2-3x-5)

    b.(x+y)^2(x-y)^2

    c. (x^2+1)(2x^2-3x-5)


    (simplify the following expression)
    d. (125p^12q^-14r^22/25p^8q^6r^-15)^-4

    Let f(x)=x1/x Find and simplify f(a+h)-f(a)/h

    (a+b)^2 = a^2+2ab+b^2

    you need to show some effort with these ... (a) thru (c) are just grunt-work multiplication. (d) involves using exponent laws.

    your last problem needs the expression for f(x) fixed ... x1/x is nonsense.
