Question

Add.
Your answer should be an expanded
polynomial in standard form.
(d2 + 6d + 9) + (d3 + 6d + 9) =​

Answer 1

Answer:

d5+12d+18

answer may be

Answer 2

$Addition \: of \: ( d^{2} + 6d + 9) + ( d^{3} + 6d + 9) \\= d^{2} + 6d + 9 + d^{3} + 6d + 9\\= d^{3} + d^{2} + 6d + 6d + 9 + 9 \\= d^{3} + d^{2} + (6+6)d + 18 \\= d^{3} + d^{2} + 12d + 18$

Therefore.,

$\red{ Standard \: form \: of \: the \: polynomial}$

$\green { = d^{3} + d^{2} + 12d + 18}$
