Question
A. perfect square trinomial formulaB. difference of perfect squares formula
Solution
A. The formula for a perfect square trinomial is (a+b)² = a² + 2ab + b² or (a-b)² = a² - 2ab + b². This is when a trinomial is the square of a binomial.
B. The formula for the difference of perfect squares is a² - b² = (a+b)(a-b). This is when the difference between the squares of two terms can be factored into the product of the sum and difference of the two terms.
