Question 553688
{{{x^3 - 3x^2 + x - 3 = 0}}}
FACTORING BY GROUPING
{{{(x^3 - 3x^2) + (x - 3) = 0}}} --> {{{x^2(x - 3) + (x - 3) = 0}}} --> {{{(x^2+1)(x - 3)}}}
The real solution is the solution to {{{x-3=0}}} --> {{{x=3}}}
The imaginary solutions are the solutions to
{{{x^2+1=0}}} --> {{{x=i}}} and {{{x=-i}}}
