Apply formula: Difference of squares formula is a2−b2=(a−b)(a+b). Here, 36x2 is (6x)2 and 100 is 102.
Use difference of squares: Apply the difference of squares formula to get (6x−10)(6x+10).
Factor out common factor: Factor out the common factor of 4 from both terms in the product to get 4(3x−5)(3x+5).
Check answer choices: Check the answer choices to find the equivalent expression.
