Question

what must be added to x⁴+2x³-2x²+x+1 so it is perfectly divisible by x²+x-2​

Answer 1

Step-by-step explanation:

x²+x-2)x⁴+2x³-2x²+x+1(x²+x-1

(-)x⁴(-)x³(+)-2x²

x³+0.x² +x+1

(-)x³(-)x²(+)-2x

-x²+3x+1

(+)-x²(+)-x(-)2

4x-1

4x-1 must be subtracted From x⁴+2x³-2x²+x+1 so that x²+x-2 divides it completely.
