pls,, help me

The polynomial have real roots.

Step-by-step explanation:

The second-order polynomial required to be analyzed is . From Algebra we remember that second-order polynomials of the form can be solved by the Quadratic Formula, of which we can determined if their roots are either real or complex by the ressource of the discriminant, defined as:

(1)

Roots are real if and only if , otherwise roots are complex.

If we know that , and , then the value of the discriminant is:

The polynomial have real roots.
