Hi! For page 120 question 8 in the pwn book, is there any other way to find the answer without using a Calculator? I tried using a calculator but it took me a long time to find the answer. In addition, is there any other way to find that there is only one solution other than graphing or plugging the x values back into the equation?

Hi! How do you do question 2 on page 100 from the functions section? I reviewed the solution in the back of the book but still don’t understand.

Hi! On q8 page 149 (polynomials), what is happening in D? Why is it true?

Hi Mike! In SAT official test 1, Q 29 (in the math calculator section), how do you solve this problem? I don’t quite understand the explanation/concepts mentioned in the book.

29)For a polynomial p(x), the value of p(3) is -2. Which of the following must be true about p(x)?

A) x-5 is a factor of p(x).

B) x-2 is a factor of p(x).

C) x+2 is a factor of p(x).

D) The remainder when p(x) is divided by x-3 is -2.

(Also what does PWN stand for?)
