Question
Find roots of polynomial $$ p(x) = 4x^2+6x-9 $$
Answer
The roots of polynomial $ p(x) $ are:
$$ \begin{aligned}x_1 &= 0.9271\\[1 em]x_2 &= -2.4271 \end{aligned} $$Explanation
The solutions of $ 4x^2+6x-9 = 0 $ are: $ x = -\dfrac{ 3 }{ 4 }-\dfrac{ 3 \sqrt{ 5}}{ 4 } ~ \text{and} ~ x = -\dfrac{ 3 }{ 4 }+\dfrac{ 3 \sqrt{ 5}}{ 4 }$.
