Quadratic Review
3 daysReview solving quadratic equations by factoring, completing the square, and the quadratic formula. Practice computing and interpreting the discriminant.
Substitution in Nonlinear Systems
4 daysPractice substituting a linear equation into a quadratic, simplifying to standard form, and solving. Start with integer solutions.
Discriminant Analysis
3 daysUse the discriminant to determine the number of intersection points without fully solving. Practice setting D = 0 for tangency problems.
Vieta's Formulas and Shortcuts
3 daysApply sum and product of roots to answer SAT questions efficiently without finding individual roots.
Circle-Line and Special Systems
4 daysSolve systems involving circles, absolute value, and rational functions. Recognize when domain restrictions affect the solution count.
SAT Practice and Timed Drills
3 daysWork through mixed SAT-style nonlinear systems under timed conditions. Focus on identifying the fastest solution strategy for each question type.
