Identify Factoring Technique: Determine the appropriate factoring technique for 4w2−1. Since we have a difference of squares, we can use the formula a2−b2=(a−b)(a+b).
Identify Squares in Expression: Identify the terms in the expression 4w2−1 as squares.4w2 can be written as (2w)2 because 2w×2w=4w2.1 can be written as 12 because 1×1=1.So, 4w2−1 is in the form of a2−b2 where a=2w and 4w20.
Apply Difference of Squares Formula: Apply the difference of squares formula to factor the expression.Using a=2w and b=1, we get:(2w)2−12=(2w−1)(2w+1).
