Factor 4x^2-121

Problem

4*x2−121

Solution

1. Identify the expression as a difference of two squares, which follows the pattern a2−b2=(a−b)*(a+b)

2. Determine the square root of the first term, 4*x2 which is 2*x

3. Determine the square root of the second term, 121 which is 11

4. Substitute the values a=2*x and b=11 into the difference of squares formula.

Final Answer

4*x2−121=(2*x−11)*(2*x+11)
