Question

If alpha amd beta are the zeroes of the polynomial x^2-2x-15 then form a quadratic polynomial whose zeroes are2alpha and 2beta.

Answer 1

sum of zeroes = 2alpha + 2beta = 2[alpha +beta]                                                product of zeroes = 2alpha*2beta = 4alphabeta                                                           formula;-   k [ X^2 - [SUM OF ZEROES ]X  +PRODUCT OF ZEROES ]                 SO EQUATION =   K  [x^2 - 2[alpha +beta]x +4alphabeta ]                                       do not give thanks to me because i know that iam great
