Relation between Roots and Coefficients

Quadratic equation of Class 11

Relation Between Roots And Coefficients.

If α, β are the roots of the equation ax2 + bx + c = 0, then α+β = and

αβ = Relation between Roots and Coefficients. By writing ax2 + bx + c = a the expression can be interpreted as a{x2 - x (sum of the roots) + product of the roots} = 0 or a

(x - α) (x - β) = 0.
