Question

Question is down below

Answer 1

B

Explanation:

Given

p(x) = x² - 2
`√(2)` x + 1, then

p(2
`√(2)` )= (2
`√(2)` )² - 2
`√(2)`(2
`√(2)` ) + 1 = 8 - 8 + 1 = 1 → B

Answer 2

B

Explanation:

p(x) = x² - 2√2x + 1

p(2√2) = (2√2)² - 2√2*2√2 + 1

=2²*(√2)² - 2*2*√2*√2 + 1

= 4 *2 - 4*2 + 1

= 8 - 8 + 1

= 1
