Algebra Shortcuts: Solving Symmetric Equations and Value-Putting Techniques
How to use value substitution (x=0, 1, -1) and symmetric identities to solve complex polynomial problems in seconds for SSC CGL & CHSL.
- If number of variables > number of equations, assume arbitrary non-zero values for extra variables.
- Master the fundamental expansion: a³ + b³ + c³ - 3abc = (a+b+c)(a²+b²+c²-ab-bc-ca).
- If a + b + c = 0, then a³ + b³ + c³ = 3abc.
The Value-Putting Revolution in Algebra
90% of algebraic identities tested in competitive exams are valid for all real numbers. Substituting simple values like 0, 1, or 2 bypasses multi-line algebraic factorization instantly.
