Factor Binomial as difference of square

What is the Difference of Two Squares?

Difference of two squares means a square number is getting subtracted from another square number. Every difference of square can be factored using this formula.

a² - b² = (a + b)(a - b)

Every polynomial that is a difference of squares can be factored by applying the following formula:

a² - b² = (a + b)(a - b)

Note that a and b in the pattern can be any algebraic expression. For example, for a=x and b=2, we get the following:

x² - 2² = (x + 2)(x - 2)

Factored terms that contain additional differences of two squares will also be factored.

Here are the steps required for factoring a difference of squares:

  • 1. Take any polynomial having two terms.
  • 2. Find the greatest common factor of the terms.
  • 3. Make the given polynomial in the format of difference of squares.
  • 4. Use the formula a² - b² = (a + b)(a - b) and substitute the values in the formula.
  • 5. Solve the factors to get the answer.

Factoring Difference Square Polynomial with Example


Question: Find factoring of 64-9x² using the difference of squares.


The given polynomial is 64-9x²

64-9x² = 8²-(3x)²

Difference of squares formula is a² - b² = (a + b)(a - b)

Place the values in the formula

8²-(3x)² = (8+3x)(8-3x)

So, factors of 64-9x² are (8+3x) and (8-3x)
