Study for Quiz 11, which will cover Completing the Square, Section 12.1, and Section 11.8. (MathZone extra credit: Sections 11.8 and 12.1). Here are some tips for the quiz:

The result of completing the square is an expression in the form a(x – h)² + k (or, in "Part 1" it will only be (x – h)² + k). The result does does not look like "x = 5 or x = 2" unless you are using completing the square as a technique, probably in sidework, to solve an equation.

In Section 12.1, the Square Root Property says that x² = c is solved by x = √c or x = –√c. Checking is not required to use this method of "taking a square root of both sides." (This is different than squaring both sides, Section 11.7, when checking is required.)

Begin studying for the final exam. See Final Review. Remember to take the COMPASS test by Saturday, December 5. You may take the COMPASS test beginning Friday, November 20.
