Use the factorization theorem to determine whether \(x-\frac{1}{2}\) is a factor of \(f(x) = 2x^{4}-x^{3}=2x-1\).

Answers (1)


Step 1
If \(x-\frac{1}{2}\) is a factor the the remainder when f(x) divided by it will be zero.
Put \(x-\frac{1}{2}=0\)
Step 2
Substitute \(x=\frac{1}{2}\) in f(x).
Thus the remainder is zero.
\(x-\frac{1}{2}\) is a factor of f(x)
