please solve fast it's urgent please ​

Answer 1

Answer:

The polynomial is x⁴-2x³+3x²+x-2

Step by step explanation:

Let the polynomial be added x

x⁴+2x³-2x²+x-1 + X = x²+2x-3

X= x²+2x-3-[ (x⁴+2x³-2x²+x-1) ]

X= x²+2x-3 - x⁴-2x³+2x²-x+1

X= x⁴-2x³+2x²+x²+2x-x-3+1

X= x⁴-2x³+3x²+x-2

So simply x⁴-2x³+3x²+x-2 must be added to x⁴+2x³-2x²+x-1 to get x²+2x-3
