Identify binomial and formula: Identify the binomial to be squared and the special case formula.The given binomial is (3v−3), 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.In the binomial (3v−3), a is 3v and b is 3.
Apply binomial formula: Apply the square of a binomial formula to expand (3v−3)2. Using the formula (a−b)2=a2−2ab+b2, we get: (3v−3)2=(3v)2−2(3v)(3)+(3)2
Simplify expression: Simplify the expression by performing the calculations.(3v)2−2(3v)(3)+(3)2=9v2−2×3×3v+9=9v2−18v+9
