Okay this is easier than you think!
if (x - 2) equals [tex]\sqrt{5}[/tex]
then that means [tex](x-2)^{2}[/tex] = [tex]\sqrt{5} ^ {2}[/tex]
Anything under a square root when sqared, is itself
[tex]\sqrt{5} ^{2} = 5[/tex]
so the value of [tex](x-2)^{2}[/tex] = 5
I hope I helped! Comment if you have questions or vote this answer as the brainliest ! :)
