For IRRATIONAL ROOTS: x2 – 6x + 7 = 0 roots are 3 +√2 and 3 –√2. sum = 6 and product = 7. For COMPLEX ROOTS: x2 – 4x + 5 = 0 roots are 2 + i and 2 – i sum = 4 and product = 5. For the stubborn sceptics, if this last equation does not really have solutions then how come these “fictitious” solutions add together to make 4 and ...
