Question

Solve square root of x plus 2 end root minus 2 equals x

Answer 1

\[\sqrt{x+2}-2=x\]?

Answer 2

Use symbols not words.

Answer 3

best i can do is

sqrt(x+2) -2 = x

Answer 4

@JonnyVonny

Yes!!

Answer 5

^that "sqrt(x+2) - 2 = x"

is perfectly fine, easy to read. First add 2 to both sides

Then, squrare both sides

Answer 6

sqrt(x+2) = 2x?

Answer 7

What is x + 2 equal to? x+2. Not 2x, you can't combine unlike terms.

Answer 8

Ah right I see, I never really succeeded at math >_>
x + 2, subract 2 from the the x + 2?

Answer 9

See the steps I posted above, there was only two.

Answer 10

x=1

Answer 11

x=1 will not work in this equation. And show your work.

sqrt(x+2) - 2 = x

after adding 2 to both sides

sqrt(x+2) = x + 2

now square both sides.

Answer 12

squaring sqrt(x+2) would be sqrt(x+2)^2 ?

Answer 13

would it be no solution

Answer 14

Well, you have:\[\sqrt{2x+2}=2+x \rightarrow 2x+2=(2+x)^2\]
From then, you factor out the square, and get x to one side, then solve.

Answer 15

(2x+1)(2x-1) ?

Answer 16

Nope... you seem to be getting things very mixed up.
