Let a, b, c be complex numbers such that the Im (c) = 0, Im(b) does not=0, Im(a) does not =0. Suppose that a^4=b^4=c, a does not = b and Re(a) does not equal Re(b) Is the answer
a) z^2- c = (z-a)(z-b)
b) z^4- c = (z - a)(z-b)(z - a*) (z - b*) where a* and b* are conjugates of a and b, respectively.
c)
z^4- c = (z - a)^2(z-b)^2

d)
z^3- c = (z - a)(z-b)(z-c)

Scenario: susan wants to make 2 square flags to sell at a crafts fair. the fabric she wants to buy is 3 meters wide. she doesn't want any fabric left over. what's the least amount of fabric she should buy? question: which equation will susan solve her problem? note: let x represent the length of 1 side of the flag. options: 1) 2x^2 = 4x 2) 8 +2x = 2(4x) 3) 2 * 2 = 4 * 2 4) 4x^2 -2x = 0
