What is the product?

[tex]\left(-2x - 9y^2\right)(-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 expressions [tex]\((-2x - 9y^2)\)[/tex] and [tex]\((-4x - 3)\)[/tex] by distributing each term.

### Step-by-step Solution:

1. Distribute each term in the first polynomial with each term in the second polynomial:

[tex]\((-2x)\)[/tex] times [tex]\((-4x)\)[/tex] gives:
[tex]\[ (-2) \times (-4) \times x \times x = 8x^2 \][/tex]

[tex]\((-2x)\)[/tex] times [tex]\((-3)\)[/tex] gives:
[tex]\[ (-2) \times (-3) \times x = 6x \][/tex]

[tex]\((-9y^2)\)[/tex] times [tex]\((-4x)\)[/tex] gives:
[tex]\[ (-9) \times (-4) \times y^2 \times x = 36xy^2 \][/tex]

[tex]\((-9y^2)\)[/tex] times [tex]\((-3)\)[/tex] gives:
[tex]\[ (-9) \times (-3) \times y^2 = 27y^2 \][/tex]

2. Combine all the terms obtained after distribution:

[tex]\[ 8x^2 + 6x + 36xy^2 + 27y^2 \][/tex]

Thus, the product of [tex]\((-2x - 9y^2)\)[/tex] and [tex]\((-4x - 3)\)[/tex] is:

[tex]\[ 8x^2 + 6x + 36xy^2 + 27y^2 \][/tex]

So, the correct answer is:

[tex]\[ 8x^2 + 6x + 36xy^2 + 27y^2 \][/tex]

This corresponds to the option: [tex]\( 8x^2 + 6x + 36xy^2 + 27y^2 \)[/tex] from the given choices.
