Which operation shows that polynomials are a closed system under addition? (1 point) Responses (5x2+2x+1)+(−2x2+6x+4)=−3x2+8x−3 (5x2+2x+1)+(−2x2+6x+4)=3x2+8x+5 (5x2+2x+1)+(−2x2+6x+4)=(−2x2+2x+4)+(5x2+6x+1)
Which operation shows that polynomials are a closed system under subtraction?(1 point) Responses (2x2+6x+1)−(3x2+3x+9)=5x2+9x+10 (2x2+6x+1)−(3x2+3x+9)=(2x2+6x−4)−(3x2+3x+4) (2x2+6x+1)−(3x2+3x+9)=2x2+6x+1−3x2−3x−9
not the answer
Which operation shows that polynomials are a closed system under addition?(1 point) Responses (2x2+6x+1)+(3x2+3x+9)=(2x2+3x+1)+(3x2+6x+9) (2x2+6x+1)+(3x2+3x+9)=5x2+9x+10 (2x2+6x+1)+(3x2+3x+9)=(2x2+3x2)+(6x+3x)+(1+9) (2x2+6x+1)+(3x2+3x+9)=−x2+3x−8
Which operation shows that polynomials are a closed system under addition?(1 point) Responses (2x2+6x+1)+(3x2+3x+9)=(2x2+3x+1)+(3x2+6x+9) left parenthesis 2 x squared plus 6 x plus 1 right parenthesis plus left parenthesis 3 x squared plus 3 x plus 9 right
