Answer :
Let's find the product of the given expressions: [tex]\((-2x - 9y^2)(-4x - 3)\)[/tex].
To multiply these two expressions together, you will apply the distributive property, often referred to as FOIL (First, Outside, Inside, Last) for binomials.
1. First Terms: Multiply the first terms of each binomial:
[tex]\[
(-2x) \cdot (-4x) = 8x^2
\][/tex]
2. Outside Terms: Multiply the outer terms of the binomials:
[tex]\[
(-2x) \cdot (-3) = 6x
\][/tex]
3. Inside Terms: Multiply the inner terms of the binomials:
[tex]\[
(-9y^2) \cdot (-4x) = 36xy^2
\][/tex]
4. Last Terms: Multiply the last terms of each binomial:
[tex]\[
(-9y^2) \cdot (-3) = 27y^2
\][/tex]
Now, combine all the results:
[tex]\[
8x^2 + 6x + 36xy^2 + 27y^2
\][/tex]
So the product of [tex]\((-2x - 9y^2)(-4x - 3)\)[/tex] simplifies to:
[tex]\[
8x^2 + 6x + 36xy^2 + 27y^2
\][/tex]
Among the given choices, this matches:
[tex]\[
8x^2 + 6x + 36xy^2 + 27y^2
\][/tex]
Therefore, this is the correct product of the expressions.
