Which of the following is a requirement for a trinomial to be factored as a perfect square? a. the coefficient for the x term must be twice the square root of the first term. b. the coefficient for the x term must be twice the square root of the last term. c. the coefficient for the x term must be twice the product of the square roots of the first and last terms. d. the coefficient for the x term must be half the product of the square roots of the first and last terms.

Step-by-step explanation:

The right answer is B.

A perfect square has the form , if we develop this expression would be

Notice when a trinomial is a perfect square, the second term is twic the square root of the third term, becase , and twice means , now in our example, .

Therefore, the right answer is B.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
