Week 7 Discussion Questions Please post a reply to DQ1 in the Main Forum. Please read all parts of the question carefully. Post a response to the following: How do you know if a quadratic equation will have one, two, or no solutions? How do you find a quadratic equation if you are only given the solution? Is it possible to have different quadratic equations with the same solution? Explain. Provide your classmate’s with one or two solutions with which they must create a quadratic equation. Consider responding to your classmates by creating an equation from their solutions. Show that your equation should yield the appropriate number of solutions. If other equations exist with the same solution, provide the alternate equation and provide an explanation. You may want to view responses to the solutions you posted and guide your classmate’s if necessary. How do you know if a quadratic equation will have one, two, or no solutions? If a, b, and c are integers, then the discriminant, b²- 4ac of ax² + bx + c = 0 determines the number and type of the solutions as follows. 1. If b²- 4ac is positive then the square root of a positive number is also some positive number. Therefore, in the numerator of the quadratic formula we will get two values: (-b + the square root) and (-b - the square root). So, when b²- 4ac > 0
