Identify Binomial and Formula: Identify the binomial to be squared and the special case formula to use.The given expression is (p−4)2, which is in the form of (a−b)2.Special case: (a−b)2=a2−2ab+b2
Identify a and b: Identify the values of a and b in the binomial.In the expression (p−4)2, compare it with (a−b)2 to find:a=pb=4
Apply Binomial Formula: Apply the square of a binomial formula to expand (p−4)2. Using the formula (a−b)2=a2−2ab+b2, we get: (p−4)2=p2−2(p)(4)+42
Simplify Expression: Simplify the expanded expression.p2−2(p)(4)+42= p2−8p+16
