Answer:
[tex]8x^2+6x+36xy^2+27y^2[/tex]
Step-by-step explanation:
Given expression,
[tex](-2x -9y^2)(-4x -3)[/tex]
By associative property,
[tex]=-2x(-4x -3)-9y^2(-4x -3)[/tex]
Again by associative property,
[tex]=-2x(-4x)-2x(-3)-9y^2(-4x)-9y^2(-3)[/tex]
[tex]=8x^2+6x+36xy^2+27y^2[/tex]
Hence,
[tex](-2x -9y^2)(-4x -3)=8x^2+6x+36xy^2+27y^2[/tex]
