- "Completing the Square,
part 2" from handout or Web
- Pages 824–825 and
page 829
- Section 11.8
- Written Assignment #11:

* Don't use a calculator.
Give an exact answer; don't approximate.
- 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.)

memorized. In addition to using it
to solve equations, you must be able to write down the quadratic
formula, which would be ALL of the following:

- You may solve an equation by
any method if none is specified.
Be aware that factoring is often easiest, so you may want
to review factoring (Chpt. 6 or Review F).
