What formula allows you to compute the product of the solutions in a quadratic equation?

In a quadratic equation of the standard form ( ax^2 + bx + c = 0 ), the solutions (or roots) can be found using the quadratic formula, which is ( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} ). To determine the product of the solutions, Vieta's formulas can be applied.

According to Vieta's formulas, the product of the roots (solutions) ( r_1 ) and ( r_2 ) of the quadratic equation is given by the formula ( \frac{c}{a} ). This means that the product of the solutions is equal to the constant term ( c ) divided by the coefficient of the ( x^2 ) term ( a ).

Understanding this relationship helps in quickly calculating the product of the roots without needing to find the roots themselves, thereby providing a useful tool in solving problems related to quadratic equations. Hence, the option representing this relationship is correct.
