Free SAT Nonlinear equations in one variable and systems of equations in two variables Practice Questions
Nonlinear equations and systems on the SAT means quadratics, absolute-value equations, and systems where one equation is not a line. Questions ask for the solutions, for how many exist, or for where two curves intersect.

How the SAT tests nonlinear equations in one variable and systems of equations in two variables
You solve by factoring, completing the square, the quadratic formula, or substitution, and you count solutions using the discriminant or a graph.
Where the points go
Reporting one solution when an absolute-value or squared equation has two, and losing the negative root.
