Things To Learn
- Develop facility with graphical interpretations of systems of equations and the meaning of their solutions on those graphs.
- Use the distance formula to find the distance between the centers of two circles and thereby determine whether the circles intersect in 0, 1, or 2 points.
- Convert the equation of a circle in general form to the center-radius form by completing the squares and, thus, find the radius and center.
- Convert the center-radius form to the general form by removing parentheses and combining like terms.
- Understand how to solve and graph a system consisting of two quadratic equations in two variables.
