Factor a^2-25

Problem

a2−25

Solution

1. Identify the expression as a difference of two squares, which follows the pattern x2−y2

2. Determine the square roots of each term, where x2=a2 gives x=a and y2=25 gives y=5

3. Apply the formula for the difference of squares: x2−y2=(x−y)*(x+y)

4. Substitute the values a and 5 into the formula to obtain the factored form.

Final Answer

a2−25=(a−5)*(a+5)
