Question

Consider the quadratic equation x2+5x+11=0. What is the discriminant of the quadratic equation?

Answer 1

The discriminant of a quadratic equation $a{x}^{2} +bx+c=0$ is given by ${b}^{2}-4ac$.
Plugging in, we get ${(1)}^{2} -4(5)(11)=1-220=\boxed{-219}$.
...Trivial plugging in; really no thought required. I don't like seeing questions like these in math class.
