Question

alpha and beta are the zeros of the polynomial f of X equal to x square - 5 x + K such that Alpha minus beta is equal to 1 find the value of k

Answer 1

alpha +beeta=-b/a
=-(-5)/1=5
(alpha -beeta)whole square=(alpha+beeta)whole square-4.alpha.beeta
(1)square=(5)square-4.k
4k=24
k=24/4
k=6
