Factoring Methods:
From: | To: |
Factoring completely means breaking down an algebraic expression into its simplest multiplicative components. This process reveals the expression's roots and is fundamental in solving equations.
Common factoring methods include:
Process:
Applications: Solving equations, simplifying expressions, finding roots/zeros, analyzing polynomial behavior, and calculus operations.
Instructions: Enter polynomial expressions in standard form (e.g., "x^2-9" or "2x^2+5x-3"). The calculator will attempt to factor completely.
Q1: What does "factor completely" mean?
A: It means breaking down an expression until all factors are irreducible (can't be factored further).
Q2: Can all expressions be factored?
A: All polynomials can be factored over complex numbers, but some are irreducible over real numbers (e.g., x²+1).
Q3: What's the difference between factoring and expanding?
A: Factoring writes an expression as a product, while expanding writes products as sums.
Q4: How do I factor expressions with higher degrees?
A: For degrees >2, try factoring by grouping, sum/difference of cubes, or rational root theorem.
Q5: Does order matter in factored form?
A: No, (x+2)(x+3) is equivalent to (x+3)(x+2) by the commutative property.
