(x + 1)(x - 15) gives roots of -1 and 15, and a = 14;
(x + 5)(x - 3) gives roots of -5 and 3, and a = 2.

Could you please solve xsquared plus 5x minus 46 equals 0 and talk through it?
Well it does not have any roots at the range of real numbers (cause 25-4*46 is less than 0..) and the imaginary roots shall be + and - : -5+sqrt(184)*i -5-sqrt(184)*i ------------------ ------------------- 2 2
