Question

what is the value of the discriminant of the polynomial 4x^2+7x+4?

Answer 1

The discriminant is referring to b^2-4ac
When a function is in the form of y = ax^2+bx+c

Answer 2

So in this case:

4x^2+7x+4
b^2-4ac
(7)^2 - (4*4*4)

Answer 3

thank you

Answer 4

\[ax^2+bx+c=0\]\[a, b \in \mathbb{R} \space ; \space \space a \neq 0\]\[\text{Discriminant}=D=\color{blue}{\Delta}=\color{red}{b^2-4ac.}\]
