Show that the equation $a x^{2}+b x+c=0$ where $a, b, c$ are real numbers connected by the relation $4 a+2 b+c=0$ and $a b>0$ has real roots.
If the roots of the quadratic equation $\frac{a}{x+a^{2}-a}+\frac{b}{x+b^{2}-b}=1$ are equal in magnitude but opposite in sign, prove that $\left(a^{2}+b^{2}\right)=2(a+b)$
Show that $x=a-b i$ is a solution to the equation $x^{2}-2 a x+\left(a^{2}+b^{2}\right)=0$.
