Question

alpha, beeta and gamma are zeroes f the cubic polynomial x3-2x2×qx-r. If alpha + beta = 0 then show that 2q=r

Answer 1

Alpha + beeta + Gama =2
0+ gama = 2
Gama=2

Alpha beeta +beeta gama + gama alpha = q
Alpha beeta + gama(alpha + beeta) = q
Alpha beeta + 0 = q
Alpha beeta =q


Alpha *beeta*gama= r
q *gama =r
q *2= r
2q=r
