Complete the table of products.
`[["First monomial"/"Second monomial",2x,-5y,-3x^2,-4xy,7x^2y,-9x^2y^2],[2x,...,...,...,...,...,...],[-5y,...,...,...,...,...,...],[-3x^2,...,...,...,...,...,...],[-4xy,...,...,...,...,...,...],[7x^2y,...,...,...,...,...,...],[-9x^2y^2,...,...,...,...,...,...]]`

Explanation

To complete the table of products for the given monomials, we will multiply each monomial in the rows by each monomial in the columns. Below is the step-by-step solution:

### Step-by-Step Solution:

1. **Multiply 2x by each monomial in the first column:**
- \( 2x \times 2x = 4x^2 \)
- \( 2x \times -5y = -10xy \)
- \( 2x \times -3x^2 = -6x^3 \)
