    x(2x squared-x-3)+ 1(2x squared-x-3)
    x.2x squared+x.x+x.3+2x squared-x-3
    2x cube+x squared+3x+2x squared-x-3
    5x squared-2x squared-3x

    Your notation is extremely awkward. We normally write x to a power as
    x^power like x^3 is x cubed
    Now I will do it your way but you have errors starting with the sign in the first line
    x(2x squared-x-3)+ 1(2x squared-x-3)
    should be
    x(2x squared-x-3) - 1(2x squared-x-3)
    then
    x*2xsquared -x*x -3x -2xsquared +x+3
    or
    2 x cubed - 3 x squared -2 x +3
