Understanding Factoring
Factoring is the process of breaking down a polynomial expression into a product of simpler expressions. It's the reverse of expanding or multiplying terms. For example, x² + 5x + 6 can be factored as (x + 2)(x + 3).
Types of Factoring
- Common Factor: When all terms share a common factor (e.g., 2x² + 4x = 2x(x + 2))
- Difference of Squares: When the expression is in the form a² - b² (e.g., x² - 4 = (x+2)(x-2))
- Perfect Square Trinomials: When the expression is a perfect square (e.g., x² + 2x + 1 = (x + 1)²)
- General Trinomials: Expressions in the form ax² + bx + c (e.g., x² + 5x + 6 = (x + 2)(x + 3))
Steps in Factoring
- Identify the type of expression you're dealing with
- Look for common factors first
- Check if it's a special pattern (difference of squares, perfect square)
- For quadratic expressions (ax² + bx + c):
- Find two numbers that add to b and multiply to ac
- Use these numbers to split the middle term
- Group terms and factor by pairs
Common Mistakes to Avoid
- Forgetting to check for common factors first
- Not recognizing special patterns
- Making arithmetic errors when finding factors
- Forgetting to check your answer by expanding the factors
Use x^2 or x² for squared terms
