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.

1. It will depend on the value of b^2-4ac, the part under the square root sign, often called D for discriminant
If D > 0 --- 2 real roots
if D=0 ---- 1 real root
if D< 0 --- 2 imaginary or complex roots
