Quadratic Equations lec 4

A quadratic equation is chosen from the set of all quadratic equations which are unchanged by squaring the roots. The chance that the chosen equation has equal root, is

If alpha and beta are the roots of a quadratic equation such that alpha+beta=2, alpha^4+beta^4=272 , then the quadratic equation is

The quadratic equation whose one root is - (i)/(4) :

Solve the following equations by using the general expression for a quadratic equation: x^2 +4ix-4=0

The quadratic equation whose one root is (-3+ i sqrt7)/(4) is
