Question

add the following polynomials
2-3x²,3x-x³,1-3x+x²​

Answer 1

Step-by-step explanation:

(2-3x²)+(3x-x³)+(1-3x+x²)

2-3x²+3x-x³+1-3x+x²

-x³-3x²+x²+3x-3x+2+1

-x³-2x²+3

Answer 2

(2-3x^2)+(3x-x^3)+(1-3x+x^2)

=2-3x^2+3x-x^3+1-3x+x^2

=2+1-3x^2+x^2+3x-3x-x^3

=3-2x^2-x^3

so,the sum is -x^3-2x^2+3
