Question

F(x)= x^2 + 4x - 5Can you calculate the discriminant for f(x) and state what it means, please.

Answer 1

`f(x)=x^2+4x-5`

The discrimiant in a quadratic equation is the part in the quadratic equation under the root

quadratic equation:

`x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a}`

The discriminant is:

`b^2-4ac`

The discriminant can be possitive, negative or cero and indicates the numbe
