Question 1144346
.


My dear visitor / "student"


In your post, &nbsp;the polynomial &nbsp;&nbsp;P(d) = {{{6d^3 + 5d^2 + 12d + 10}}}  &nbsp;&nbsp;<U>HAS NO any relation</U> &nbsp;to the remaining part of the problem.


You simply mixed two parts of different problems in one.


I don't know if you did it by mistake or intentionally, &nbsp;but my duty is to inform you 

(and the next generations of students, &nbsp;who, &nbsp;probably, &nbsp;will read this post from the archive in the future) 
about this sad circumstance.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Have a nice day (!)
