Find roots of polynomial $$ p(x) = 18x^2+14x-63 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 1.5219\\[1 em]x_2 &= -2.2997 \end{aligned} $$Explanation
The solutions of $ 18x^2+14x-63 = 0 $ are: $ x = -\dfrac{ 7 }{ 18 }-\dfrac{ 13 \sqrt{ 7}}{ 18 } ~ \text{and} ~ x = -\dfrac{ 7 }{ 18 }+\dfrac{ 13 \sqrt{ 7}}{ 18 }$.
