Q. Find the product. Simplify your answer.(4z+4)(4z−4)
Identify Form: Identify the form of the expression.The expression (4z+4)(4z−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 (4z+4)(4z−4) with (a+b)(a−b). a=4zb=4
Apply Formula: Apply the difference of squares formula.Using the values of a and b, we can expand (4z+4)(4z−4) using the formula.(4z+4)(4z−4)=(4z)2−(4)2
Simplify Expression: Simplify the expression.(4z)2−(4)2= (4z×4z)−(4×4)= 16z2−16
