Which expression is equivalent to 7-2z-4 [z^3 - z^3+4z^2+11z+14/z+2]? a. -4z^3+4z^2+6z+35 b. -4z^3+4z^2-10z-21 c. -18z-5 d. -18z+10 plz you

To simplify the expression we proceed as follows: 7-2z-4 [z^3 - z^3+4z^2+11z+14/z+2]=7-2z-4z^3+4z^3-16z^2-44z-56/z-8putting like terms together: =(7-8)+(-2z-44z-16z^2)+(-4z^3+4z^3)-56/z=-1-46z-16z^2-56/z=multiplying through by z we get: =-z-46z^2-16z^3-56from above answer we see that non of the expression from the choices given is equal to our final answer
