Need help with a radical equation. Open question for equation. Will give medals.
\[\sqrt{2x+9}-\sqrt{x+1}=\sqrt{x+4}\]
square both sides then you will have to isolate the radical and do it again it is a pain
whats would it look like after you squared it. thats all i need
first off another easy inspection tells you the answer is zero when you square you get \[2x+9-2\sqrt{2x+9}\sqrt{x+1}-(x+1)=x+4\]
combine like terms put everything without the radical on the other sides then square again
ok thanks.
yw don't forget to square the \(-2\)
I'm sorry. @satellite73 Could you please do the second step? Then I think I'll be good.
\[2x+9-2\sqrt{2x+9}\sqrt{x+1}-(x+1)=x+4\] distribute the \(-\)sign \[2x+9-2\sqrt{2x+9}\sqrt{x+1}-x-1=x+4\] combine like terms \[x+8-2\sqrt{2x+9}=x+4\]
it is late and i messed up the last one \[x+8-2\sqrt{2x+9}\sqrt{x+1}=x+4\]
@satellite73 Sorry again. :P One more step then I'm almost certain I'll be good.
