GATE | GATE-CS-2016 (Set 1) | Question 9
If f(x) = 2x7 + 3x – 5
Which of the following is a factor of f(x)?
(A) (x3 + 8)
(B) (x – 1)
(C) (2x – 5)
(D) (x + 1)
Answer: (B)
Explanation:
f(x) = 2x7 + 3x - 5
= 2x7 - 2x + 5x - 5
Putting x = 1, we get f(x) = 0.
So, x-1 is a factor of f(x).
Thus, B is the correct choice.
