Find the Discriminant 4x^2-17x+3

$4 x^{2} - 17 x + 3$

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 $c$ .

${(- 17)}^{2} - 4 (4 \cdot 3)$

Step 3

Evaluate the result to find the discriminant.

Simplify each term.

Raise $- 17$ to the power of $2$ .

$289 - 4 (4 \cdot 3)$

Multiply $- 4 (4 \cdot 3)$ .

Multiply $4$ by $3$ .

$289 - 4 \cdot 12$

Multiply $- 4$ by $12$ .

$289 - 48$

Subtract $48$ from $289$ .

$241$
