If the equation z4+a1z3+a2z2+a3z+a4=0 where a1,a2,a3,a4 are real coeff – InterviewSolution

1.	If the equation z4+a1z3+a2z2+a3z+a4=0 where a1,a2,a3,a4 are real coefficients different from zero, has a pure imaginary root, then the expression a3a1a2+a1a4a2a3 has the value equal to
Answer» If the equation $z^{4} + a_{1} z^{3} + a_{2} z^{2} + a_{3} z + a_{4} = 0$ where $a_{1}, a_{2}, a_{3}, a_{4}$ are real coefficients different from zero, has a pure imaginary root, then the expression $\frac{a_{3}}{a_{1} a_{2}} + \frac{a_{1} a_{4}}{a_{2} a_{3}}$ has the value equal to
