4z3(3z-1)+7(3z-1)

    what is the goal? to simplify? if so it would be:
    12z^4-4z^3+21z-7

    z^2 means z squared, z^3 z cubed, etc.
    i assumed that the 4z3 at the beginning was four z cubed...

    4z^3*(3z-1)+7(3z-1)=

    4z^3*(3z-1)+(7*3)*z+7*(-1)=

    4z^3*3z+4z^3*(-1)+21z-7=

    12z^4-4z^3+21z-7

    By the way in google type:
    Expessions Simplifier

    When you see list of results click on:
    Expessions Simplifier and Solver-Algebra com

    When page be open in rectacangle type your equation 4z3(3z-1)+7(3z-1)
    and click option SOLVE OR SIMPLIFY

    You will se solution step-by-step
