## anonymous 5 years ago √x + 2 = 2 then (x + 2)² =

1. anonymous

see this questions is following: first square both sides we get

2. anonymous

$(\sqrt{x}+2)^{2}p =2^{2}$

3. anonymous

p = 2sorry

4. anonymous

ohk now we know (a+b)^2 = $a^{2}+2ab +b ^{2}$

5. anonymous

$hence, (\sqrt{x}^{2}+2(\sqrt{x}+2)+2^{2} = 4$

6. anonymous

now we get $x +2\sqrt{x}+4+4=4$

7. anonymous

$x +2\sqrt{x} = 4$

8. anonymous

now we will solve (x=2)^2

9. anonymous

$x ^{2}+4x +4$

i will continue my answer after some time i have to go seriously sorry

Thank you for all your help,
