A.) x = -6 + or - the square root of 30
B.) x = 6 + or - the square root of 30
C.) x = -6 + or - the square root of 6
D.) x = 6 + or - the square root of 6

Answer 2

I don't even remember the completing-the-square method! Let me refresh my memory then I'll get back to you.

Answer 3

Ok thanks :) @Hulk_Smash

Answer 4

Maybe this sites might help:

Answer 5

I already looked at both sites earlier and i still dont understand how to solve the problem @Hulk_Smash

Answer 6

(x^2 +2* x* 6+6^2) -6^2+6=0 (we are add and subtract 6^2 )

Answer 7

(x+6)^2 -36+6=0

Answer 8

do u following

Answer 9

yes

Answer 10

r u there

Answer 11

so x^2 + 6 = 0? @dayakar

Answer 12

no

Answer 13

(x+6)^2-30 =0

Answer 14

(x+6)^2 =30

Answer 15

\[x+6 = + or -\sqrt{30}\]

Answer 16

so x = -6 + or - square root of 30? @dayakar

Answer 17

no

Answer 18

x+6= sqrt30 or x+6 =-sqrt30

Answer 19

but you subtract 6 from both sides

Answer 20

your options are wrong

Answer 21

\[x=-6+\sqrt{30}\]
or

Answer 22

\[x= -6-\sqrt{30}\]

Answer 23

is it clear

Answer 24

that's what I said but ok XD thanks @dayakar
