Question

If alpa and beta are the zeroes of the polynomial x2-2x-15 then form a quadratic polynomial whose zeroes are 2alpha and 2 beta

Answer 1

hey..

here is ur answer

Answer 2

factors of x2-2x-15 by factorization are 5 &-3
so, alpha=5 then 2alpha=10,beta=-3 then 2beta=-6
the Polynomial=x2-4x-60
