Question

use square root property to solve this:
(x+8)^2=9 step by step descriptions are loved :) thanks!! ^_^

Answer 1

i dunno, sorry. Actually. I should know, but im multi-tasking.

Answer 2

can you ask around for me? I need to get these done soon, its hard when i dont understand anything :(

Answer 3

I'm an awesome spammer. Watch me.

Answer 4

root both sides and then subtract 8.

Answer 5

cant you see that 3^2=9

Answer 6

see? I am an awesome spammer.

Answer 7

Langrange, also (-3)^2 = 9, so that isnt a complete solution

Answer 8

I think so

Answer 9

The point being that 9 is a perfect square

Answer 10

I'm sorry :( I'm not math smart,what does this mean? is this problem impossible to solve?

Answer 11

Root both sides first. Remember + and -
(x+8) = 3 and -(x+8) = 3
I'm sure you can solve those 2 equations to find both values of x.

Answer 12

is the answer 5?

Answer 13

(x+8)^2=9 take square roots of both sides
(x+8) = +3
also
(x+8) = -3 (this is because (+3)^2 =9 and (-3)^2 = 9

So let's take
(x+8) = +3 subtract 8 from both sides
x = -5

now let's take
(x+8) = -3 subtract 8 from both sides
x = -11

So there are TWO solutions, x = -5 and x = -8.
You can see why when you graph it:
By the way I made the picture by going to http://www.wolframalpha.com and typing

(x+8)^2=9

Answer 14

so -5 and -11? Are these correct. And thank you ^_^

Answer 15

woops nevermind i see it XD sorry ^^;
