Find the Discriminant x^2+10x+25=0

$x^{2} + 10 x + 25 = 0$

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 $c$ .

$10^{2} - 4 (1 \cdot 25)$

Step 3

Evaluate the result to find the discriminant.

Simplify each term.

Raise $10$ to the power of $2$ .

$100 - 4 (1 \cdot 25)$

Multiply $- 4 (1 \cdot 25)$ .

Multiply $25$ by $1$ .

$100 - 4 \cdot 25$

Multiply $- 4$ by $25$ .

$100 - 100$

Subtract $100$ from $100$ .

$0$
