If `P(x)=x^2-2sqrt(2)x+1` then `p(2sqrt(2))` is equal to?

If p(x)=x^2-5sqrt5x+1 then p(sqrt5)=

If p(x)=2x^2-5 sqrt(3)x+5 then find p(5sqrt(3))

If p(x)= x^(2) - 2 sqrt(2) x + 1 , find p ( 2sqrt(2))

(i) If p(x)=3x^(2)-5x+6 , find p(2) . (ii) If q(x)=x^(2)-2sqrt(2)x+1 , find q(2sqrt(2)) . (iii) If r(x)=5x-4x^(2)+3 find r(-1) .

lim_(x to 2) (x - 2)/(sqrt(x) - sqrt(2)) is equal to
