Find the Discriminant 6x^2-5x+2=0

$6 x^{2} - 5 x + 2 = 0$

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 $c$ .

${(- 5)}^{2} - 4 (6 \cdot 2)$

Step 3

Evaluate the result to find the discriminant.

Simplify each term.

Raise $- 5$ to the power of $2$ .

$25 - 4 (6 \cdot 2)$

Multiply $- 4 (6 \cdot 2)$ .

Multiply $6$ by $2$ .

$25 - 4 \cdot 12$

Multiply $- 4$ by $12$ .

$25 - 48$

Subtract $48$ from $25$ .

$- 23$
