Solved problems on theory of equations |topic: relation between roots and coefficients| IIT JEE CBSE

Описание: In this video, concept of relation between the roots and coefficients of polynomial equations are with solved examples

If α,β and 1 are the roots of x^3-2x^2-5x+6=0, then find α and β

If α,β,γ are the roots of x^3-2x^2+3x-4=0 , then find
Σα^2 β^2
Σαβ(α+β)

If α,β,γ are the roots of x^3+px^2+qx+r=0 , then find
Σ 1/(α^2 β^2 )
(β^2+γ^2)/βγ+(γ^2+α^2)/γα+(α^2+β^2)/αβ
(β+γ-3α)(γ+α-3β)(α+β-3γ)
Σα^3 β^3
