Factor Binomial as difference of square

Detailed Solution for Finding the Factoring of Binomial b^2-81 using Difference of Square

Given equation is b^2-81

Convert the equation into the form of a² - b²

So, b^2-81 = (b)²-(9)²

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

After substituting the values in the formula

(b)²-(9)²

=(b+9)(b-9)

Therefore, the factors for the equation b^2-81 are (b+9)(b-9)

FAQs on Factoring Binomial of b^2-81 by Difference of Squares

1. How do you find the factor of the difference of two squares?

When an expression can be viewed as the difference between two perfect squares, i.e. a²-b², then we can factor it as (a+b)(a-b). For example, x²-25 can be factored as (x+5)(x-5). This method is based on the pattern (a+b)(a-b)=a²-b², which can be verified by expanding the parentheses in (a+b)(a-b).


2. What is the Factoring of Binomial b^2-81 using the Difference of Squares method?

The Factoring of Binomial b^2-81 using the Difference of Squares method is (b - 9) (b + 9).


3. How can you use the difference of squares to find the factors of b^2-81?

The difference of squares formula is a²-b² = (a + b)(a - b). Convert the given equation b^2-81 and find the factors.


4. How to Factor Binomial b^2-81 by Difference of Squares on a calculator?
