Cheat Sheet
- Quadratic Equation Mastery -
Get comfortable with factoring, completing the square, and the quadratic formula x = [ - b ± √(b² - 4ac)]/(2a); this trifecta is the backbone of solving hard algebra problems (source: MIT OpenCourseWare). Practice a few examples like x² - 5x+6=0 to cement the steps. Mnemonic: "x equals negative b, plus or minus the square root…" to recall the quadratic formula swiftly.
- Rational Expressions & Partial Fractions -
Learn to simplify complex fractions by factoring numerators and denominators - e.g., (x² - 1)/(x² - x - 2) becomes (x - 1)/(x - 2) after canceling (x+1). When facing super hard algebra questions involving decompositions, partition into A/(x - 2)+B/(x+1) to solve integrals or limits (Paul's Online Math Notes). Keep domain restrictions top of mind to avoid extraneous roots.
- Gaussian Elimination for Linear Systems -
Use augmented matrices and row operations (swap, scale, add) to reach reduced row-echelon form; this systematic method cracks very hard algebra problems involving three or more variables (Khan Academy). For example, transform [[1,2, - 1|3],[2,1,1|4]] into simpler rows to back-substitute solutions. A quick tip: always create a leading 1 in each pivot position first.
- Inequalities & AM - GM Tricks -
Master proving and solving inequalities like the Arithmetic Mean - Geometric Mean rule: (a+b)/2 ≥ √(ab). This is a powerful tool in challenging inequality problems found in math competitions (Art of Problem Solving). Remember the mnemonic "AMEEGEEM," pronounced "em-gee-em," to recall AM ≥ GM in super hard algebra puzzles.
- Function Composition & Inverses -
Understand f(g(x)) and how to find f❻¹(x) by swapping x and y then solving; e.g., if f(x)=2x+3, its inverse is f❻¹(x)=(x - 3)/2. Many hard algebra problems hinge on nesting functions or reversing operations flawlessly (source: University of California, Berkeley Math). Always check f(f❻¹(x))=x to validate your inverse.
