    complex numbers question

    You can use the relationships of roots and coefficients to find the values of 'a' and 'b'. The Sum Of Roots: (a + bi) + (a - bi) + (a + 2bi) + (a - 2bi) = -4 a + bi + a - bi + a + 2bi + a - 2bi = -4 4a = -4 a = -1 The Product Of Roots: (a + bi) (a - bi) (a + 2bi) (a - 2bi) = 10 (a^2 + b^2)...
