Identify values of a and b: Identify the values of a and b in the binomial (2a−4)2. In this case, a=2a and b=4.
Apply binomial square formula: Apply the square of a binomial formula to expand (2a−4)2. Using the formula (a−b)2=a2−2ab+b2, we get: (2a−4)2=(2a)2−2⋅(2a)⋅(4)+(4)2
Simplify the expression: Simplify the expression by performing the calculations.(2a)2−2⋅(2a)⋅(4)+(4)2= 4a2−16a+16
