    x^2 - 5x + 13 = 0

    Use the quadratic formula.

    x = (5 ± √(25 - 52))/2

    x = (5 ± √(-27))/2

    x = (5 ± 3i√3)/2

    x1 = 5/2 - ((3√3)/2)i

    x2 = 5/2 + ((3√3)/2)i

    Multiply suited and backside by utilising potential of the conjugate of three+2i, it extremely is 3-2i. (7-5i)(3-2i) / (3+2i)(3-2i) (21-14i-15i+10i²) / (9-6i+6i-4i²) (11-29i) / 13. so which you have been suitable suited. the respond would be written as (11/13) - (29/13)i for particular.
