1. Problem Description

The problem asks to expand the product of the binomial (2+3w)(2 + 3w) and the trinomial (w2+6w+9)(w^2 + 6w + 9) and express the result as a polynomial in standard form.

2. Solution Steps

To expand the expression (2+3w)(w2+6w+9)(2 + 3w)(w^2 + 6w + 9), we use the distributive property (also known as FOIL method when multiplying two binomials). We multiply each term in the first factor (2+3w)(2 + 3w) by each term in the second factor (w2+6w+9)(w^2 + 6w + 9).
(2+3w)(w2+6w+9)=2(w2+6w+9)+3w(w2+6w+9)(2 + 3w)(w^2 + 6w + 9) = 2(w^2 + 6w + 9) + 3w(w^2 + 6w + 9)
=2w2+12w+18+3w3+18w2+27w= 2w^2 + 12w + 18 + 3w^3 + 18w^2 + 27w
Now, we combine like terms:
=3w3+(2w2+18w2)+(12w+27w)+18= 3w^3 + (2w^2 + 18w^2) + (12w + 27w) + 18
=3w3+20w2+39w+18= 3w^3 + 20w^2 + 39w + 18
The polynomial in standard form is 3w3+20w2+39w+183w^3 + 20w^2 + 39w + 18.

3. Final Answer

3w3+20w2+39w+183w^3 + 20w^2 + 39w + 18
