Identify binomial and formula: Identify the binomial to be squared and the special case formula.The given expression is (4q−4)2, which is in the form of (a−b)2.Special case: (a−b)2=a2−2ab+b2
Identify values of a and b: Identify the values of a and b. Compare (4q−4)2 with (a−b)2. a=4qb=4
Apply binomial square formula: Apply the square of a binomial formula to expand (4q−4)2.(a−b)2=a2−2ab+b2(4q−4)2=(4q)2−2(4q)(4)+(4)2
