Approach Determination: Determine the approach to factor 16t2−25. We can observe that 16t2 and 25 are both perfect squares, and they are being subtracted from each other. This suggests that we can use the difference of squares formula, which is a2−b2=(a−b)(a+b).
Identify Form: Identify 16t2−25 in the form of a2−b2.16t2 can be written as (4t)2 because 4t×4t=16t2.25 can be written as 52 because 5×5=25.So, 16t2−25 can be rewritten as (4t)2−52.
Apply Formula: Apply the difference of squares formula to factor the expression.Using the formula a2−b2=(a−b)(a+b), we substitute a with 4t and b with 5.(4t)2−52=(4t−5)(4t+5).
Final Factored Form: Write the final factored form.The factored form of 16t2−25 is (4t−5)(4t+5).
