Approach Determination: Determine the approach to factor 16u2−25. We can observe that the expression is a difference of squares, which can be factored using the formula a2−b2=(a−b)(a+b).
Form Identification: Identify 16u2−25 in the form of a2−b2. 16u2 can be written as (4u)2 because 4u×4u=16u2. 25 can be written as 52 because 5×5=25. So, 16u2−25 is in the form of (4u)2−52.
Formula Application: Apply the difference of squares formula to factor the expression.Using the formula a2−b2=(a−b)(a+b), we substitute a with 4u and b with 5.(4u)2−52=(4u−5)(4u+5).
Final Factored Form: Write the final factored form.The factored form of 16u2−25 is (4u−5)(4u+5).
