Question
Find roots of polynomial $$ p(x) = 9x^2-60x+60 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 5.4415\\[1 em]x_2 &= 1.2251 \end{aligned} $$Explanation
The solutions of $ 9x^2-60x+60 = 0 $ are: $ x = \dfrac{ 10 }{ 3 }-\dfrac{ 2 \sqrt{ 10}}{ 3 } ~ \text{and} ~ x = \dfrac{ 10 }{ 3 }+\dfrac{ 2 \sqrt{ 10}}{ 3 }$.
