Find roots of polynomial $$ p(x) = 10x^2-12x+7 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= \frac{ 3 }{ 5 }+\frac{\sqrt{ 34 }}{ 10 }i\\[1 em]x_2 &= \frac{ 3 }{ 5 }- \frac{\sqrt{ 34 }}{ 10 }i \end{aligned} $$Explanation
The solutions of $ 10x^2-12x+7 = 0 $ are: $ x = \dfrac{ 3 }{ 5 }+\dfrac{\sqrt{ 34 }}{ 10 }i ~ \text{and} ~ x = \dfrac{ 3 }{ 5 }-\dfrac{\sqrt{ 34 }}{ 10 }i$.
