Answer:

The discriminant is -71

The discriminant is less than zero, the equation has no real roots

Explanation:

Given the equation:

[tex]3m^2-13m+20=0[/tex]

The discriminant is given as:

[tex]D=b^2-4ac[/tex]

where a = 3, b = -13, c = 20

[tex]\begin{gathered} D=(-13)^2-4(3)(20) \\ \\ =169-240 \\ =-71 \end{gathered}[/tex]

The discriminant is less than zero, the equation has no real roots
