You can use the same techniques (substitution and linear combination) to solve quadratic systems. Finding Points of Intersection. Find the points of intersection of the graphs of x2 y2 13 and y x 1. SOLUTION. To find the points of intersection, substitute x 1 for y in the equation of the circle. Practice and Reinforcement. 40 min. To practice solving quadratic equations, I use Solving Quadratics 3 Ways so that students are expected to use each method. Many students see the efficiency of using the Quadratic Formula and then begin using it for every quadratic equation but I stress the importance of staying flexible. **8-7 practice solving quadratic systems** System of quadraticquadratic equations. The solutions to a system of equations are the points of intersection of the lines. For a system with two quadratic equations, there are 4 cases to consider: 2 solutions, 1 solution, no solutions, and infinite solutions. Basic concepts: System of linearquadratic equations.
