Answer:
[tex]10u^{3}+4u^{2}-2u+10[/tex] or [tex]2(5u^{3}+2u^{2}-u+5)[/tex]
Step-by-step explanation:
we have
[tex](4u^{3}+4u^{2} +2)+(6u^{3}-2u+8)[/tex]
step 1
Group terms that contain the same variable
[tex](4u^{3}+6u^{3})+(4u^{2})+(-2u)+(2+8)[/tex]
step 2
Combine like terms
[tex](10u^{3})+(4u^{2})+(-2u)+(10)[/tex]
step 3
Eliminate parenthesis
[tex]10u^{3}+4u^{2}-2u+10[/tex]
step 4
Factor the number [tex]2[/tex]
[tex]2(5u^{3}+2u^{2}-u+5)[/tex]
