If f(x) = 2x7 + 3x – 5, which of the following is a factor of f(x)?
Correct Answer: B
Question 9 Explanation:
f(x) = 2x7 + 3x – 5
For (x – a) to be a factor of f(x)
f(a) = 0
From options,
Only a=1, satisfies the above equation
∴ (x – 1) is a factor of f(x).
For (x – a) to be a factor of f(x)
f(a) = 0
From options,
Only a=1, satisfies the above equation
∴ (x – 1) is a factor of f(x).
(x 3 +8)
(x-1)
(2x-5)
(x+1)
