Solving Nonlinear Systems of Two Equations with 2 variables.
This collection of videos provides many examples solving non-linear systems of equations where the degree is 2--exponent on variable is 2 as in x^2 or xy. Most problems are shown using the substitution or elimination method, as well as showing the graphical representation of the solutions--points of intersection on the graphs.
