WAEC 2017
If \((2x^{2} - x - 3)\) is a factor of \(f(x) = 2x^{3} - 5x^{2} - x + 6\), find the other factor
- A. (x - 2)
- B. (x - 1)
- C. (x + 1)
- D. (x + \(\frac{3}{2}\))
Correct Answer: A. (x - 2)
Explanation
Divide \((2x^{3} - 5x^{2} - x + 6)\) by \((2x^{2} - x - 3)\) to get the other factor. Be careful of sign conventions.
