Identify values of a and b: Identify the values of a and b in the binomial (2x−4). In the expression (2x−4)2, a is 2x and b is 4.
Apply binomial square formula: Apply the square of a binomial formula to expand (2x−4)2. Using the formula (a−b)2=a2−2ab+b2, we get: (2x−4)2=(2x)2−2⋅(2x)⋅4+42
Simplify expansion terms: Simplify each term in the expansion.(2x)2=4x2 (since 2x×2x=4x2)2×(2x)×4=16x (since 2×2x×4=16x)42=16 (since 4×4=16)
Combine simplified terms: Combine the simplified terms to get the final answer.(2x−4)2=4x2−16x+16
