How do you solve a complex number problem

Find real values of the number a for which a.i is a solution of the polynomial equation. ... u,v and w are the three roots of the equation z3 - 1 = 0 . ... Calculate all solutions of |z-1|.|z-1|=1. ... The equation z3 - (n + i) z + m + 2 i = 0. ... Let z' the conjugate complex number of z.

No, she was very close though.

Step-by-step explanation:

Add 81, 87, 91, and 141 and you get 400. Then add 100, 100, 100 and 150 and get 450. then you put 400/450 which equals 88.88... But Jada needs a 80% so she was close but not quite there. :P
