Therefore, equating real and imaginary parts separately for left and right sides of this equation, we get a system of two equations with two unknowns. 0 = x2 − y2.

Weba, b < 0. If a and b are negative, then the square root of them must be imaginary: ⁺√a = xi. ⁺√b = yi. x and y must be positive (and of course real), because we are dealing with the principal square roots. ⁺√a • ⁺√b = xi (yi) = -xy. -xy must be a negative real number because x and y are both positive real numbers. WebThe answers of using de Moivre's formula are correct but it may also be instructive to try and find the square roots directly using (a + bi)2 = 9 + 4i (say) and solve for a and b or even just use the quadratic formula directly, which will give you an appreciation for why we use de Moivre's formula. – user2055 Jun 9, 2011 at 19:38 Add a comment original species art
