Find the Discriminant x^2+9x+14=0

$x^{2} + 9 x + 14 = 0$

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 $c$ .

$9^{2} - 4 (1 \cdot 14)$

Step 3

Evaluate the result to find the discriminant.

Simplify each term.

Raise $9$ to the power of $2$ .

$81 - 4 (1 \cdot 14)$

Multiply $- 4 (1 \cdot 14)$ .

Multiply $14$ by $1$ .

$81 - 4 \cdot 14$

Multiply $- 4$ by $14$ .

$81 - 56$

Subtract $56$ from $81$ .

$25$
