Answer: [tex]4x^3-2x^2+20x-10[/tex]
Step-by-step explanation:
(c·d)(x) means c(x)*d(x). The little circle filled in means to multiply c and d. If it was an open circle, then it would mean c(d(x)). Since the problem you stated was a closed circle, we would multiply c and d.
[tex](4x-2)(x^2+5)=4x^3+20x-2x^2-10[/tex]
This answer is technically correct, but it is always better to put them in order.
[tex]4x^3-2x^2+20x-10[/tex]
If this is not what the problem is asking for, meaning it was looking for (cod)(x), then let me know. I will be happy to help!
