Question

can u help me with this one sqrt(x+2)=sqrt(x)+1

Answer 1

square both sides

Answer 2

i could have sworn mininaya write a very nice answer to this one. square both sides

Answer 3

so then x+2 = x +2sqrt(x)+1 no?

Answer 4

\[\sqrt{x+2}=\sqrt{x}-1\]
\[x+2=(\sqrt{x}+1)^2=\sqrt{x}\sqrt{x} + 2\sqrt{x}+1=x+2\sqrt{x}+1\]\]

Answer 5

so sqrt(x) = 1/2?

Answer 6

x = 1/4

Answer 7

so subtracting x from both sides gives
\[2=2\sqrt{x}+1\] subtract 1 gives \[1=2\sqrt{x}\] divide by 2 to get
\[\frac{1}{2}=\sqrt{x}\] square again to get
\[\frac{1}{4}=x\]

Answer 8

what light said

Answer 9

ok thanks
