About Expression Simplification

Mathematical expression simplification involves applying algebraic rules to make an expression clearer and more concise while maintaining its value.

Common Simplification Techniques
  • Combining like terms: Adding or subtracting terms with the same variables and exponents.
  • Factoring: Rewriting expressions as products to reveal common factors.
  • Expanding: Multiplying out brackets to remove parentheses.
  • Applying algebraic identities: Using standard formulas like (a+b)² = a² + 2ab + b².
  • Reducing fractions: Dividing numerator and denominator by common factors.
  • Rationalizing denominators: Eliminating radicals from denominators.
Algebraic Identities
Square of Sum
(a + b)² = a² + 2ab + b²
Square of Difference
(a - b)² = a² - 2ab + b²
Difference of Squares
a² - b² = (a + b)(a - b)
Cube of Sum
(a + b)³ = a³ + 3a²b + 3ab² + b³
Cube of Difference
(a - b)³ = a³ - 3a²b + 3ab² - b³
Sum of Cubes
a³ + b³ = (a + b)(a² - ab + b²)
Difference of Cubes
a³ - b³ = (a - b)(a² + ab + b²)
Common Algebraic Identities:
(a + b)² = a² + 2ab + b²
(a - b)² = a² - 2ab + b²
a² - b² = (a + b)(a - b)
(a + b)³ = a³ + 3a²b + 3ab² + b³
(a - b)³ = a³ - 3a²b + 3ab² - b³
a³ + b³ = (a + b)(a² - ab + b²)
a³ - b³ = (a - b)(a² + ab + b²)
