c) In order to find the the other two solutions, Sally should use which method to solve the quadratic? A Graphing B Square Root Method C The Quadratic Formula D Factoring

To find the other two solutions of a quadratic equation, Sally should use:<br /><br />(C) The Quadratic Formula<br /><br />The Quadratic Formula is a reliable method for solving any quadratic equation of the form \( ax^2 + bx + c = 0 \). It provides the solutions directly and works regardless of whether the quadratic can be factored easily or not. The formula is given by:<br /><br />\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \]<br /><br />This method ensures that all possible solutions are found.
