# Product of roots formula

The product of the roots of a quadratic equation is equal to the constant term (the third term), divided by the leading coefficient. You will discover in. Product of the roots = c/a = c. Which gives us this result. x2 ? (sum of the roots)x + (product of the roots) = 0.Using the formulas above, we have ?+?=2 and ??=72. Now (?+?)2=?. Sum of the roots = 4 + 2 = 6. Product of the roots = 4 * 2 = 8. We can use our formulas, to set up the following two equations. So our final quadratic. According to quadratic formula, the roots of quadratic equation a x 2 + b x + c = 0 are represented by Alpha ( ? ) and Beta ( ? ). The product of roots ? and.

## Sum and product of roots

Sum of the roots = ?b/a = -b Product of the roots = c/a = c. Which gives us this result. x2 ? (sum of the roots). Hence, sum of the roots is 5 and the product of the roots is 8. Was this answer helpful? upvote 0.Sum of the roots = 4 + 2 = 6. Product of the roots = 4 * 2 = 8. We can use our formulas, to set up the following two equations. So our final quadratic. Sum of the roots ? and ? · ? + ? = ? b + b 2 ? 4 a c 2 a + ? b ? b 2 ? 4 a c 2 a displaystylealpha+beta=frac{{-{b}+sqrt{{{b}^{2}-{4}{a}{c}}}}}{{{2}{a}}. 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. The product.
