    Solve the equation z^2+z+1=0 using z=(x,y) and the basic definitions. (Hint: Note that y does not equal 0 because the equation X^2+X+1 does not equal 0 for any real number x.)

    a. z1=--1+j(Sqrt3)/2 and z2=-1/2-j(Sqrt3)/2
    b. z1=-1/2+j(Sqrt3)/2 and z2=-1/2-j(Sqrt3)/2
    c. z1=-1/3+j(Sqrt3)/2 and z2=-j(Sqrt3)/2
    d. z1=3/2+j(Sqrt3)/2 and z2=-1/2-j(Sqrt3)/4.
