Question

solve the square root of x+4 = the square root of x plus the square root of 2

Answer 1

\[\sqrt{x+4}=\sqrt{x}+\sqrt2\]?

Answer 2

yes

Answer 3

answer not obvious for this one
square both sides first
the left will be \(x+4\)
the right you have to multiply out \((\sqrt{x}+\sqrt2)(\sqrt{x}+\sqrt2)\)
