If p(x)= x2 – 2√2x + 1, then p(2√2) is equal to(A) 0(B) 1(C) 4√2(D) 8√2 +1

Answer»

(B) 1

Explanation:

According to the question,

p(x) = x2 – 2√2x + 1

To get p(2√2),

We substitute x = 2√2,

p(2√2) = (2√2)2 – (2√2 × (2√2)) + 1

= (4 × 2) – (4 × 2) + 1

= 8 – 8 + 1

= 1

Hence, option B is the correct answer
