Q. Find the product. Simplify your answer. (2f+4)(2f−4)
Identify Form: Identify the form of the expression.The expression (2f+4)(2f−4) is in the form of (a+b)(a−b), which is a difference of squares.Special case: (a+b)(a−b)=a2−b2
Identify Values: Identify the values of a and b. Compare (2f+4)(2f−4) with (a+b)(a−b). a=2fb=4
Apply Formula: Apply the difference of squares formula to expand (2f+4)(2f−4).(a+b)(a−b)=a2−b2(2f+4)(2f−4)=(2f)2−(4)2
