Question
Find roots of polynomial $$ p(x) = 5x^2+28x-145 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 3.2696\\[1 em]x_2 &= -8.8696 \end{aligned} $$Explanation
The solutions of $ 5x^2+28x-145 = 0 $ are: $ x = -\dfrac{ 14 }{ 5 }-\dfrac{\sqrt{ 921 }}{ 5 } ~ \text{and} ~ x = -\dfrac{ 14 }{ 5 }+\dfrac{\sqrt{ 921 }}{ 5 }$.
