Factor n^2-25

Problem

n2−25

Solution

1. Identify the expression as a difference of two squares, which follows the pattern a2−b2

2. Determine the values of a and b by taking the square root of each term.

3. Recognize that n2 is (n)2 and 25 is (5)2

4. Apply the formula for the difference of squares, a2−b2=(a−b)*(a+b) substituting n for a and 5 for b

Final Answer

n2−25=(n−5)*(n+5)
