What Must Be Added to X4 + 2x3 − 2x2 + X − 1 , So that the Resulting Polynomial is Exactly Divisible by X2 + 2x − 3?

What must be added to x⁴ + 2x³ − 2x² + x − 1 , so that the resulting polynomial is exactly divisible by x²+ 2x − 3?

Sum

Thus, (x - 2) should be added to (\[x^4 + 2 x^3 - 2 x^2 + x - 1\] ) to make the resulting polynomial exactly divisible by \[(x^2 + 2x - 3)\]
