Factor y^2-25

Problem

y2−25

Solution

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

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

3. Find a by calculating √(,y2)=y

4. Find b by calculating √(,25)=5

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

6. Substitute y for a and 5 for b into the formula.

Final Answer

y2−25=(y−5)*(y+5)
