Find the Discriminant b^2-4ac

$b^{2} - 4 a c$

Step 1

The discriminant of a quadratic is the expression inside the radical of the quadratic formula.

$b^{2} - 4 (a c)$

Step 2

Substitute in the values of $a$ , $b$ , and $c$ .

$0^{2} - 4 (1 (- 4 a c))$

Step 3

Evaluate the result to find the discriminant.

Simplify each term.

Raising $0$ to any positive power yields $0$ .

$0 - 4 (1 (- 4 a c))$

Multiply $- 4 a c$ by $1$ .

$0 - 4 (- 4 a c)$

Multiply $- 4$ by $- 4$ .

$0 + 16 a c$

Add $0$ and $16 a c$ .

$16 a c$
