sum and product of roots of quadratic equation Thus the sum of roots of a quadratic equation is given by the negative ratio of coefficient of begin array l x end array begin array l x 2 end array The product of roots is given by ratio of the constant term and the coefficient of
The sum of the roots alpha and beta of a quadratic equation are alpha beta b a The product of the roots alpha and beta is given by alpha beta c a It s also important to realize that if alpha and beta are roots then x alpha x beta 0 Given a quadratic equation ax2 bx c 0 By the quadratic formulas the two roots can be represented as Sum of the Roots r1 r2 Product of the Roots r1 r2 The sum of the roots of a quadratic equation is equal to the negation of the coefficient of the second term divided by the leading coefficient
