Find roots of polynomial $$ p(x) = 5x^2+\frac{37}{2}x-22 $$

The roots of polynomial $ p(x) $ are:

$$ \begin{aligned}x_1 &= 0.9469\\[1 em]x_2 &= -4.6469 \end{aligned} $$

Step 1:

Get rid of fractions by multipling equation by $ \color{blue}{ 2 } $.

$$ \begin{aligned} 5x^2+\frac{37}{2}x-22 & = 0 ~~~ / \cdot \color{blue}{ 2 } \\[1 em] 10x^2+37x-44 & = 0 \end{aligned} $$

Step 2:

The solutions of $ 10x^2+37x-44 = 0 $ are: $ x = -\dfrac{ 37 }{ 20 }-\dfrac{\sqrt{ 3129 }}{ 20 } ~ \text{and} ~ x = -\dfrac{ 37 }{ 20 }+\dfrac{\sqrt{ 3129 }}{ 20 }$.
