Answer:
3x^10 + x^6 + 2x^2 - 4x + 8
Step-by-step explanation:
In descending order by powers of x: 3x^10 + x^6 + 2x^2 - 4x + 8
3x+8x=3333
11x=3333
X= 303
Boys 3x,so 3*303=909

The respective terms used for the lines are ~
3+(-5)x=19
Subtract 3 from both sides of the equation.
-5x= 16
Divide by -5 on both sides
X= -3.2
