Find roots of polynomial $$ p(x) = 4x^2+15x-12 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.6776\\[1 em]x_2 &= -4.4276 \end{aligned} $$Explanation
The solutions of $ 4x^2+15x-12 = 0 $ are: $ x = -\dfrac{ 15 }{ 8 }-\dfrac{\sqrt{ 417 }}{ 8 } ~ \text{and} ~ x = -\dfrac{ 15 }{ 8 }+\dfrac{\sqrt{ 417 }}{ 8 }$.
