Answer:

The discriminant is -71

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

Step-by-step explanation:

Given the equation:


3m^2-13m+20=0

The discriminant is given as:


D=b^2-4ac

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


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

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