Identify Binomial and Formula: Identify the binomial to be squared and the special case formula.The given expression is (3b+3)2, which is a binomial squared.The special case formula for the square of a binomial is (a+b)2=a2+2ab+b2.
Identify a and b: Identify the values of a and b in the binomial.In the expression (3b+3)2, a is 3b and b is 3.
Apply Binomial Formula: Apply the square of a binomial formula to expand (3b+3)2. Using the formula (a+b)2=a2+2ab+b2, we get: (3b+3)2=(3b)2+2(3b)(3)+(3)2
Simplify Expression: Simplify the expanded expression.(3b)2+2(3b)(3)+(3)2= 9b2+2(9b)+9= 9b2+18b+9
