Here are the essential concepts you must grasp in order to answer the question correctly.
Binomial Expansion
Binomial expansion refers to the process of expanding expressions that are raised to a power, particularly those in the form of (a + b)^n. The expansion can be achieved using the Binomial Theorem, which states that (a + b)^n = Σ (n choose k) * a^(n-k) * b^k, where k ranges from 0 to n. This theorem allows for systematic calculation of each term in the expansion.

Perfect Square Trinomial
A perfect square trinomial is a specific type of polynomial that results from squaring a binomial. The general form is (a + b)^2 = a^2 + 2ab + b^2. Recognizing this pattern helps simplify the process of expanding binomials, as it allows for quick identification of the resulting terms without needing to multiply each term individually.
