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 = 
. 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.
