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, we will multiply each monomial in the first row with each monomial in the first column. Here’s the step-by-step solution:

### Step 1: Multiply 2x with each monomial
- **2x * 2x = 4x²**
- **2x * -5y = -10xy**
- **2x * -3x² = -6x³**
- **2x * -4xy = -8x²y**
- **2x * 7x²y = 14x³y**
