Step 3: Factor the completed square Step 4: Use the Square Root Property
(x - 2)2 =
= -9
Take the square root of both sides, remembering the square root property (there are two square roots to consider, the
positive and the negative!)
2 - 2 =
.
Step 5: Finish solving
If your answer contains non-integer values, use fractions, not decimals.
If you need to use the square root symbol as in 5, type it using sqrt(5).
• If there are no solutions, enter no solutions.

Martha has a deck of cards. she has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight clubs, and twelve hearts. martha predicts that whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time. which activity would best allow martha to test her prediction? a. randomly draw a card from the box and see if it is a club. b. randomly draw a card. then, continue to draw another card until all eight clubs are drawn. c. randomly draw and replace a card 120 times. then, observe how close to 30 times a club is drawn. d. randomly draw and replace a card 100 times. then, observe how close to 20 times a club is drawn.
