Identify factoring technique: Determine the appropriate factoring technique for 16w2−25. Since we have a subtraction of two squares, we can use the difference of squares formula, which is a2−b2=(a−b)(a+b).
Recognize as difference of squares: Recognize 16w2−25 as a difference of squares.16w2 can be written as (4w)2 because 4w×4w=16w2.25 can be written as 52 because 5×5=25.So, 16w2−25 is in the form of a2−b2 where a=4w and 16w20.
Apply difference of squares formula: Apply the difference of squares formula to factor the expression.Using the formula a2−b2=(a−b)(a+b), we substitute a with 4w and b with 5.(4w)2−52=(4w−5)(4w+5)
Write final factored form: Write the final factored form of the expression.The factored form of 16w2−25 is (4w−5)(4w+5).
