Question

Select the two values of x that are roots of the given polynomial below x^2+3x+5

Answer 1

This polynomial has no real roots, since its discriminant < 0. This can be calculated as b^2-4ac = 9-4*5 = -11.


If you allow complex roots, they are:


`x = - \frac12 i (√(11) - 3i)`

and


`x = \frac12 i (√(11) + 3i)`
