Question on proving quadratic inequality 
Let $ax^2+bx+c$ = 0  be a quadratic equation and $\alpha$,$\beta$ are real roots. Condition for $\alpha < -1$ and $\beta > 1$. Show that $1 +\frac{c}{a}$ + $\left|\frac{b}{a}\right| < 0$. 

I have tried but could not prove this inequality. I want to know how to solve this. Show that I can get an idea and solve further questions myself.

Without loss of generality, let $a \gt 0$.
Now firstly,  Since $\alpha$ is a root of $f(x)$, hence $a\alpha^2+b\alpha+c=0$.
$\Rightarrow$ $\alpha = \frac {-b - \sqrt{b^2-4ac}}{2a} \lt -1$ $\Rightarrow$ $-b - \sqrt{b^2-4ac} \lt -2a$ $\Rightarrow$ $\sqrt{b^2-4ac} \gt 2a-b$ $\Rightarrow$ $b^2-4ac \gt 4a^2-4ab+b^2$ $\Rightarrow$ $a^2+ab-ac \lt 0$ $\Rightarrow$ $1-\frac ba+\frac ca \lt 0$.
Similarly, $\beta=\frac {-b+\sqrt {b^2-4ac}}{2a} \gt 1$ $\Rightarrow$ $\sqrt {b^2-4ac} \gt b+2a$ $\Rightarrow$ $b^2-4ac \gt b^2+4ab+4a^2$ $\Rightarrow$ $a^2+ab+ac \lt 0$ $\Rightarrow$ $ 1+\frac ba+\frac ca \lt 0$.
Hence, $1+\frac ca+|\frac ba| \lt 0$.
