<h2>Solving Quadratic Equations with the Quadratic Formula</h2>

<h3>Answer:</h3>

$x = 3$ and $x = \frac{1}{2}\\$

<h3>Step-by-step Explanation: </h3>

Recall:

if we have a quadratic equation, $ax^2 +bx +c = 0$ , where $a$ , $b$ and $c$ are real numbers and $a \neq 0$ , $x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}$ .

Given:

$2x^2 -7x +3 = 0$

Solving for $x$ :

$x = \frac{-(-7) \pm \sqrt{(-7)^2 -4(2)(3)}}{2(2)} \\ x = \frac{-(-7) \pm \sqrt{49 -4(2)(3)}}{2(2)} \\ x = \frac{7 \pm \sqrt{49 -24}}{4} \\ x = \frac{7 \pm \sqrt{25}}{4} \\ x = \frac{7 \pm 5}{4}$
