Subject: Find a Quadratic Equation given roots
Name: MC
Question: If you have the equation You can factor the quadratic to get and hence the roots Conversely, if you have the roots x = 1 and x = 3 you can recover the quadratic equation by forming (x  1)(x + 3) = 0. The same is true if the roots ate complex, for example suppose that the roots are 5 + 3i and 5  3i then the quadratic equation is which simplifies to Harley
