Identify binomial and formula: Identify the binomial to be squared and the special case formula to use.The given binomial is (4b−2), and we need to square it. The special case formula for the square of a binomial is (a−b)2=a2−2ab+b2.
Identify values of a and b: Identify the values of a and b in the binomial (4b−2). In the binomial (4b−2), a is 4b and b is 2.
Apply binomial square formula: Apply the square of a binomial formula to expand (4b−2)2. Using the formula (a−b)2=a2−2ab+b2, we get: (4b−2)2=(4b)2−2⋅(4b)⋅2+(2)2
Simplify each term: Simplify each term in the expansion.(4b)2=16b2 (since 4b×4b=16b2)2×(4b)×2=16b (since 2×4b×2=16b)(2)2=4 (since 2×2=4)So, (4b−2)2=16b2−16b+4
