The princess examines one plant and can’t seem to locate its roots. The plant is labeled as p(x)=x^2+x+3 Which values should the
AleksAgata [21]
Let's actually find the roots, using the quadratic formula:

<span>p(x)=x^2+x+3 gives us a=1, b=1 and c=3.

                 -1 plus or minus sqrt(1^2-4(1)(3))
Then x = -----------------------------------------------          
                                           2

The discriminant here is negative, so the roots x will be complex:

              -1 plus or minus sqrt(-11)      -1 plus or minus i*sqrt(11)
       x = ---------------------------------- = -------------------------------------
                          2                                                 2

These are irrational roots; they cannot be expressed as the ratios of integers.</span>
