Question

x + 1 - 2 square root x + 4 = 0

Answer 1

\[x+1-2\sqrt{x+4}=0\]


is this what the equation is supposed to look like?

Answer 2

yes, thank you

Answer 3

no problem, so you have to isolate the x, correct?

Answer 4

yes

Answer 5

so -2 sr x + 4 = -x -1

Answer 6

ok, so the x+1 is attached? because there are no parenthesis around them so i dont believe they are attached to each other, which means you can subtract just thee one so you will get: x-2srx+4=-1

Answer 7

Then is it x squared + 16 x - 32 = -1?

Answer 8

add \(2\sqrt{x+4}\) to both sides and start with
\[x+1=2\sqrt{x+4}\] then square both sides

Answer 9

Ahhh, ok I think I see it now and in the end x = 5?
