Identify values of a and b: Identify the values of a and b. In the expression (4w−4)2, a is 4w and b is 4.
Apply binomial formula: Apply the square of a binomial formula.Using the formula (a−b)2=a2−2ab+b2, we substitute a with 4w and b with 4 to expand (4w−4)2.(4w−4)2=(4w)2−2(4w)(4)+(4)2
Simplify the expression: Simplify the expression.Now we calculate each term:(4w)2=16w2 (since 4w×4w=16w2)2(4w)(4)=32w (since 2×4w×4=32w)(4)2=16 (since 4×4=16)So, (4w−4)2=16w2−32w+16
