Question

if p (x) is equal to x square - 2 root 2 x + 1 then find the value of p(2 root 3)

Answer 1

p(x) = x² – 2√2x + 1
p(2√3) = (2√3)² – 2√2(2√3) + 1
= 12 – 4√6 + 1
= 13 – 4√6

Here is your answer
$p(x) = {x}^{2} - 2 \sqrt{2} x + 1 \\ find \: p(2 \sqrt{3} ) \: \: which \: is \\ = (2 \sqrt{3} ) {}^{2} - 2 \sqrt{2} \times 2 \sqrt{3} + 1 \\ = 12 - 4 \sqrt{6} + 1 \\ = 13 - 4 \sqrt{6}$
