Understanding Factorization
Factorization is the process of breaking down a mathematical expression into simpler components (factors) that, when multiplied together, give the original expression. For polynomials, this means expressing them as a product of simpler polynomials.

Breaking down a polynomial into factors
Think of factorization like breaking down a complex Lego structure into its individual blocks. Each block is a factor, and when you multiply them together, you get back the original structure.
Why Factorize Polynomials?
- Simplifies complex expressions
- Helps solve polynomial equations
- Useful in calculus for finding derivatives and integrals
- Essential for graphing polynomial functions
Common Factorization Methods
There are several techniques for factoring polynomials:
- Greatest Common Factor (GCF): Factor out the largest common term
- Grouping: Group terms with common factors
- Difference of Squares: a² – b² = (a + b)(a – b)
- Trinomial Factoring: For quadratic trinomials like ax² + bx + c
- Sum/Difference of Cubes: a³ ± b³ = (a ± b)(a² ∓ ab + b²)
Example: Greatest Common Factor
Factor: 6x³ + 9x²
So, 6x³ + 9x² = 3x²(2x + 3)
Solved Examples
