Algebraic expression: combination of variables, constants, and operations. Example: 3x² + 2x - 5.
Key identities: (a+b)² = a²+2ab+b². (a-b)² = a²-2ab+b². (a+b)(a-b) = a²-b². (a+b)³ = a³+3a²b+3ab²+b³.
Factoring: x²+5x+6 = (x+2)(x+3). Take out common factor first. Group method for 4 terms.
Linear equations: ax+b = c → x = (c-b)/a. Simultaneous equations solved by substitution or elimination.
