Find the Discriminant 7x^2-3x+10=0

$7 x^{2} - 3 x + 10 = 0$

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 $c$ .

${(- 3)}^{2} - 4 (7 \cdot 10)$

Step 3

Evaluate the result to find the discriminant.

Simplify each term.

Raise $- 3$ to the power of $2$ .

$9 - 4 (7 \cdot 10)$

Multiply $- 4 (7 \cdot 10)$ .

Multiply $7$ by $10$ .

$9 - 4 \cdot 70$

Multiply $- 4$ by $70$ .

$9 - 280$

Subtract $280$ from $9$ .

$- 271$
