Homework Statement
When 3x5 - ax + b is divided by x - 1 and x + 1 the remainders are equal. Given that a, b ε ℝ
(a) the value of a;
(b) the set of values of b.
Homework Equations
The Attempt at a Solution
f(1) = f(-1)
3 - a + b = -3 + a + b
6 = 2a
a = 3 ... [1]
Substitute a -3 into 3 - a + b
b = 0
Can someone please explain to me why the set of values of b would be all real numbers?
From my knowledge, I believe my way of understanding is unclear and may be incorrect.
My interpretation: b not being affected by any coefficients and that b is simply a constant in a function.
Cheers.
