Identify binomial and formula: Identify the binomial to be squared and the special case formula to use.The given expression is (v−3)2, which is in the form of (a−b)2.Special case: (a−b)2=a2−2ab+b2
Identify values of a and b: Identify the values of a and b in the binomial. Compare (v−3)2 with (a−b)2. a=vb=3
Apply binomial square formula: Apply the square of a binomial formula to expand (v−3)2. Using the formula (a−b)2=a2−2ab+b2, we get: (v−3)2=v2−2(v)(3)+32
Simplify expanded expression: Simplify the expanded expression. v2−2(v)(3)+32= v2−6v+9
