Question

If alpha, bita, r are the zeroes of the cubic polynomial p(x) =x3+2x2-3x then alpha×bita×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
