The quotient of (x4 - 3x2 + 4x - 3) and a polynomial is (x2 + x - 3). What is the polynomial?

x4 - 2x2 + 5x - 6

x2 - x + 1

x6 + x5 - 6x4 + x3 + 10x2 - 15x + 9

x4 - 4x2 + 3x

The right answer for the question that is being asked and shown above is that: "x2 - x + 1."The quotient of (x4 - 3x2 + 4x - 3) and a polynomial is (x2 + x - 3). The polynomial is this one: x2 - x + 1
