Introduction to Factoring the Difference of Squares
Factoring the difference of squares is a technique used in algebra to factorize expressions of the form a 2– b 2, where a and b represent real numbers or algebraic expressions.
The factorization formula for the difference of squares is: a 2– b 2= (a + b)(a – b)
For example, the expression 9x 2– 16 can be factored as (3x + 4)(3x – 4) using the formula.
Methods for Factoring the Difference of Squares, Factoring the difference of squares worksheet
To factor the difference of squares, follow these steps:
- Identify the terms a 2and b 2in the expression.
- Write the factors as (a + b)(a – b).
- Simplify the factors if possible.
For example, to factor 49y 2– 25, we have a 2= 49y 2and b 2= 25. Using the formula, we get (7y + 5)(7y – 5).
Applications of Factoring the Difference of Squares
Factoring the difference of squares has several applications in algebra:
- Simplifying expressions: Factoring the difference of squares can help simplify complex expressions by reducing them to simpler factors.
- Solving equations: Factoring the difference of squares can be used to solve quadratic equations that can be written in the form a 2– b 2= 0.
For example, to solve the equation x 2– 9 = 0, we can factor the left-hand side as (x + 3)(x – 3) and then set each factor equal to zero to find the solutions x = ±3.
