Determine method for factoring: Determine the appropriate method to factor the expression 16f2−25. The expression is a difference of squares, which can be factored using the formula a2−b2=(a−b)(a+b).
Identify perfect squares: Identify the terms in the expression 16f2−25 as perfect squares.16f2 is a perfect square because 16 is 4 squared and f2 is f squared, so (4f)2.25 is a perfect square because it is 5 squared, so 52.Therefore, 16f2−25 can be written as 16f21.
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 4f and b with 5.(4f)2−52=(4f−5)(4f+5).
