Outcomes

In this lesson you will

determine the sum and product of the roots of a quadratic equation
relate the coefficients of a quadratic equation to the sum and product of the roots of the corresponding quadratic equation

By the end of this section students will be able to:

derive and apply the quadratic formula
analyze the quadratic formula to connect its components to the graphs of quadratic functions
solve quadratic equations
relate the nature of the roots of quadratic equations and the x- intercepts of the graphs of corresponding functions
represent non-real roots of quadratic equations as complex numbers
demonstrate an understanding of the role of irrational numbers in applications
demonstrate an understanding of the nature of the roots of quadratic equations

To be successful in this lesson, it would be helpful to know the following:
