Recognize special case: We are asked to find the square of the binomial (3q−3). The first step is to recognize that this is a special case of the algebraic identity (a−b)2, which expands to a2−2ab+b2.
Identify values of a and b: Identify the values of a and b in the binomial (3q−3). By comparing it to the general form (a−b)2, we can see that a=3q and b=3.
Apply algebraic identity: Apply the algebraic identity (a−b)2=a2−2ab+b2 to the binomial (3q−3).(3q−3)2=(3q)2−2(3q)(3)+(3)2
Simplify each term: Simplify each term in the expression (3q)2−2(3q)(3)+(3)2.(3q)2=9q2 (since (3q)×(3q)=9q2)2(3q)(3)=18q (since 2×3q×3=18q)(3)2=9 (since 3×3=9)
Combine simplified terms: Combine the simplified terms to get the final expanded and simplified form of the square of the binomial (3q−3).(3q−3)2=9q2−18q+9
