If alphabe a repeated root of a quadratic equation f(x) = 0 and A(x),B(x) , C(x) be polynomials of degree 3,4,5 respectively , then F(x)=|(A(x),B(x),C(x)),(A(alpha),B(alpha),C(alpha)),(A^1(alpha),B^1(alpha),C^1(alpha))|

Answer»

not DIVISIBLE by `(x-alpha)`
divisible by `(x -alpha)` , not by `(x -alpha)^2`
divisible by `(x-alpha)^2` , not by F(x)
