What is the product of the expression?

[tex]\[

(-2x - 9y^2)(-4x - 3)

\][/tex]

A. [tex]\(-8x^2 - 6x - 36xy^2 - 27y^2\)[/tex]

B. [tex]\(-14x^2 - 36xy^2 + 27y^2\)[/tex]

C. [tex]\(8x^2 + 6x + 36xy^2 + 27y^2\)[/tex]

D. [tex]\(14x^2 + 36xy^2 + 27y^2\)[/tex]

Answer :

Sure! Let's find the product of the expression [tex]\((-2x - 9y^2)(-4x - 3)\)[/tex] using distributive property:

1. Distribute [tex]\(-2x\)[/tex] across the second set of parentheses:
- Multiply [tex]\(-2x\)[/tex] by [tex]\(-4x\)[/tex]:
[tex]\[
(-2x) \cdot (-4x) = 8x^2
\][/tex]
- Multiply [tex]\(-2x\)[/tex] by [tex]\(-3\)[/tex]:
[tex]\[
(-2x) \cdot (-3) = 6x
\][/tex]

2. Distribute [tex]\(-9y^2\)[/tex] across the second set of parentheses:
- Multiply [tex]\(-9y^2\)[/tex] by [tex]\(-4x\)[/tex]:
[tex]\[
(-9y^2) \cdot (-4x) = 36xy^2
\][/tex]
- Multiply [tex]\(-9y^2\)[/tex] by [tex]\(-3\)[/tex]:
[tex]\[
(-9y^2) \cdot (-3) = 27y^2
\][/tex]

3. Combine all the results together:
[tex]\[
8x^2 + 6x + 36xy^2 + 27y^2
\][/tex]

The result of the multiplication is:
[tex]\[
8x^2 + 6x + 36xy^2 + 27y^2
\][/tex]

This matches with one of the given answer choices:
[tex]\[
8x^2 + 6x + 36xy^2 + 27y^2
\][/tex]
