Answer :
To find the product of the expressions [tex]\((-2x - 9y^2)\)[/tex] and [tex]\((-4x - 3)\)[/tex], we need to distribute each term in the first expression by each term in the second expression and then simplify the result.
Let's break it down step by step:
1. Distribute [tex]\(-2x\)[/tex] to both terms in [tex]\((-4x - 3)\)[/tex]:
- Multiply [tex]\(-2x\)[/tex] by [tex]\(-4x\)[/tex]: [tex]\((-2x) \times (-4x) = 8x^2\)[/tex]
- Multiply [tex]\(-2x\)[/tex] by [tex]\(-3\)[/tex]: [tex]\((-2x) \times (-3) = 6x\)[/tex]
2. Distribute [tex]\(-9y^2\)[/tex] to both terms in [tex]\((-4x - 3)\)[/tex]:
- Multiply [tex]\(-9y^2\)[/tex] by [tex]\(-4x\)[/tex]: [tex]\((-9y^2) \times (-4x) = 36xy^2\)[/tex]
- Multiply [tex]\(-9y^2\)[/tex] by [tex]\(-3\)[/tex]: [tex]\((-9y^2) \times (-3) = 27y^2\)[/tex]
3. Combine all the terms we found:
- [tex]\(8x^2\)[/tex] from step 1
- [tex]\(6x\)[/tex] from step 1
- [tex]\(36xy^2\)[/tex] from step 2
- [tex]\(27y^2\)[/tex] from step 2
4. Write down the final expression:
- The expression is [tex]\(8x^2 + 36xy^2 + 6x + 27y^2\)[/tex]
This is the simplified product of [tex]\((-2x - 9y^2)\)[/tex] and [tex]\((-4x - 3)\)[/tex].
Let's break it down step by step:
1. Distribute [tex]\(-2x\)[/tex] to both terms in [tex]\((-4x - 3)\)[/tex]:

2. Distribute [tex]\(-9y^2\)[/tex] to both terms in [tex]\((-4x - 3)\)[/tex]:
- Multiply [tex]\(-9y^2\)[/tex] by [tex]\(-4x\)[/tex]: [tex]\((-9y^2) \times (-4x) = 36xy^2\)[/tex]
- Multiply [tex]\(-9y^2\)[/tex] by [tex]\(-3\)[/tex]: [tex]\((-9y^2) \times (-3) = 27y^2\)[/tex]

- [tex]\(8x^2\)[/tex] from step 1
- [tex]\(6x\)[/tex] from step 1
- [tex]\(36xy^2\)[/tex] from step 2
- [tex]\(27y^2\)[/tex] from step 2
4. Write down the final expression:
- The expression is [tex]\(8x^2 + 36xy^2 + 6x + 27y^2\)[/tex]
This is the simplified product of [tex]\((-2x - 9y^2)\)[/tex] and [tex]\((-4x - 3)\)[/tex].
