Step 1.1.1

Combine $\frac{1}{2}$ and $x^{2}$ .

$\frac{x^{2}}{2} - \frac{5}{4} x - 3 = 0$

Step 1.1.2

Combine $x$ and $\frac{5}{4}$ .

$\frac{x^{2}}{2} - \frac{x \cdot 5}{4} - 3 = 0$

Step 1.1.3

Move $5$ to the left of $x$ .

$\frac{x^{2}}{2} - \frac{5 x}{4} - 3 = 0$

Step 2

Once the quadratic is in standard form, the values of $a$ , $b$ , and $c$ can be found.

$a x^{2} + b x + c$

Step 3

Use the standard form of the equation to find $a$ , $b$ , and $c$ for this quadratic.

$a = \frac{1}{2}$ , $b = - \frac{5}{4}$ , $c = - 3$
