1. Solve by completing the square.

....... write as , then group first two terms and second two terms
.......

() - () = .......factor out in first group , and in second group
x(x � 2) - 2(x - 2) = 0.......factor out
(x � 2)(x - 2) = 0.......solution

2. Solve by completing the square.

write this first in standard form:

coefitients are: , , and
now apply the quadratic formula:

3. Solve by using the quadratic formula.
= �

coefitients are: , , and
now apply the quadratic formula:

4. Solve by using the quadratic formula.

coefitients are: , , and
now apply the quadratic formula:

5. Solve. ....divide both sides by
...move to the right
...., so
