Find roots of polynomial $$ p(x) = 15x^2+112x+165 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= -2.0193\\[1 em]x_2 &= -5.4473 \end{aligned} $$Explanation
The solutions of $ 15x^2+112x+165 = 0 $ are: $ x = -\dfrac{ 56 }{ 15 }-\dfrac{\sqrt{ 661 }}{ 15 } ~ \text{and} ~ x = -\dfrac{ 56 }{ 15 }+\dfrac{\sqrt{ 661 }}{ 15 }$.
