Question

write a cubic polynomial with sum, sum of the product of its zeroes taken two at a time and product of its zeroes are3,-1/2,5/4 respectively

Answer 1

Let the zeroes of the polynomial are α,β and γ

Sum of the zeroes = α+β+γ = 3

Sum of the product of the zeroes taken two at a time = αβ+βγ+αγ = -1/2

Product of zeroes = αβγ = 5/4

A cubic polynomial which has three zeroes is in the form of

x³-( α+β+γ )x²+( αβ+βγ+αγ )x - αβγ

x³-3x²-x/2-5/4
