9. W2 – 8w = 9
Solve the equation by completing square. Round your answer to the nearest hundredth

w^2-8w=9

Let B= -8.

so we add (b/2)^2 =16 to both sides to complete the square

w^2-8w+16=9+16

w^2-8w+16=25

Step 2...Factor left side

(w-4)^2 =25

Step 3 Take the sqare root

w-4=±

Step 4 :Add 4 to both sides

w-4+4=4+

w=4±

w=4+5 or w= 4-5

w=9 orv w= -1

Answer w= 9 or w = -1
