I'v been stuck on this question and I dont know how to solve it. I have to use the remainder theorem to find the answer for (4x³ - 5x² + 3x - 14) / (x² + 2x - 1).

Since I can't expand (x² + 2x - 1) so I cannot find any values for "x". Can somebody please help I have to hand this in after tomorrow.

Thanks
