Find all solutions of the eqation x^2 -2x+8=0 and express them in the fom a+bi

input the solution with b<0

the real part a equals and the imaginary part b equals

input the solution with b>0

x= -(-2)+- sqrt((-2)^2-4*-2) / 2*1

x= 2 +- sqrt (4+8) / 2

x= 2+- sqrt (12) / 2

x= 1+- sqrt 3

x = 1+sqrt 3, x = 1-sqrt 3
