Answer 1

what is a complete square?

Answer 2

add (b/2)^2

Answer 3

I did that I need a whole number I came up with 1 but it is not right

Answer 4

-6/2 = -3
then you square that (-3)^2 = 9

Answer 5

blext didnt get a 1 ;)

Answer 6

b=-6/2^2 = 36/4

Answer 7

yes; and 36/4 = 9

Answer 8

where so you get 36?

Answer 9

6^2 = 36
--------- = 9
2^2 = 4

Answer 10

formula x^-6x=-8
b=(-6/2)^2

Answer 11

36/4 =9 so I put 9 on each side of the equation?

Answer 12

welll close;

b = -6; the number you wanna add to both sides is:

(b/2)^2

Answer 13

yes; add 9 to both sides to complete the square

Answer 16

this is true I am taking this test for my last time on my math lab and want to get the correct answers.

Answer 17

the real solution is:

(bx/2ax)^2 but for the a=1 thats rather obiquitous. and the x's always cancel anyways.
