Hello,


1)x=-3 or x=1/2

2)
x1 = -2.027279411321 − 0 = -2.027279411321
x2 = 1.013639705661 + i0.28704765924
x3 = 1.013639705661 - i0.28704765924

3)
x1 = -0.86258402041244 + i1.0672228500956
x2 = -0.86258402041244 − i1.0672228500956
x3 = 0.86258402041244 + i0.92148671871903
x4 = 0.86258402041244 − i0.92148671871903
