Since 4i is a root, that automatically means -4i is also a root (complex roots always travel in pairs) So the factored form would look like <span>(x+4i)(x−4i).</span> When multiplied out this gives the polynomial <span><span>x2</span>+<span>16.</span></span>

(20n^2+N^3+10n^2) /10N^2
kirill115 [55]
Combine like terms:
n^3 + 20n^ + 10n^2
= n^3 + 30n^

Divide:
=n^3 + 30n^2/10n^2

Factor:
=n^2n + 30n^2
=n^(n + 30)
= 2^2(n + 30)/10n^2

Cancel the common factor n^2:
=n + 10/10
