Question

Zach wrote the formula w(w-1)(5w + 4) for the volume of a rectangular prism he is designing, with width w, which is always has a positive value greater than 1. Find the product and then classify this polynomial by degree and by number of terms.
Choices:)
A.) 5w^5 - w^4 - 4w^3; quintic trinomial
B.) 20w^2; quadratic monomial
C.) 5w^3 - w^2 - 4w; cubic trinomial
D.) 5w^4 - w^3 - 4w^2; quartic trinomial

Answer 1

I can usually do these but I forget how to. So I put it on here to see if someone can help me and I see @Jim766 is responding to my question. Thank you.

Answer 2

W(w-1)(5w+4)
W(w^2-1w-4)

Answer 3

Now mult times w

Answer 4

Do you see what I did?

Answer 5

in a way. it says here in my book --> Write each polynomial in standard form. then classify it by degree and by number of terms.

Answer 6

W(w^2-w-4)
W^3-w^2-4w
That is standard form
Degree would be 3, highest exponent
It's a cubic trinomial

Answer 7

Do you understand?
