Question

Solve 2(x+3)^2 -4 =6
the answer is x= -3 +- square root of 5
Just need to show the work and idk how.

Answer 1

correct :D

Answer 2

ok now we are going to work on this :D

Answer 3

since -4 does not contain the variable to solve for, move it to the right side of the equation by adding 4 to both sides
2(x+3)^2=4+6

Answer 4

add 4 and 6 to get 10
2(x+3)^2=10

Answer 5

what do you think we do next @SPHott51

Answer 6

Divide thru by 2 getting (x+3)^2 -2 = 3 now add 2 to both sides; That gives you (x+3)^2 = 5 Now take the sqrt of both sides. Giving: x + 3 = sqrt 5 Now solve for x getting you what you expected.

Answer 7

@SPHott51 you there

Answer 8

Yeah, I'm here

Answer 9

do you know what we do next :D

Answer 10

a few.. Just dont know to to solve x-3= sqrt 5 to get the x..

Answer 11

well next we divide each term in the equation by 2
2(x+3)^2/2=10/2

Answer 12

I got it now

Answer 13

ok :D
