Solve quadratic, radical, and absolute-value equations, plus mixed systems.
Nonlinear equation questions ask you to find real solutions to quadratics, radicals, absolute value, and rational equations — and to handle systems where one equation is linear and the other is nonlinear. The Digital SAT likes to hide these as graph intersections.
These are real practice questions pulled from our Digital SAT bank. Try each one before reading the highlighted correct answer.
