1
The discriminant (D) of a quadratic polynomial of the form $ax^2+bx+c$ is calculated using the following formula, where $a$, $b$ and $c$ are the coefficients of the corresponding terms
$D=b^2-4ac$
2
From the equation, we see that $a=1$, $b=4$ and $c=4$. Replacing the values of $a$, $b$ and $c$ in the previous formula, we obtain
$D=4^2+4\cdot 1\cdot -4$
3
Multiply $4$ times $1$
$4^2+4\cdot -4$
4
Multiply $4$ times $-4$
$4^2-16$
5
Calculate the power $4^2$
$16-16$
6
Subtract the values $16$ and $-16$
0
7
The discriminant of the polynomial results in
