Which two values of x are roots of the polynomial below x2-3x 5?

Answer 1

It is difficult to tell because there is no sign (+ or -) before the 5.

+5 gives complex roots and assuming that someone who asked this question has not yet come across complex numbers, I assume the polynomial is

x2 -3x - 5

The roots of this equation are: -1.1926 and 4.1926 (to 4 dp)
