Answer:
[tex]12x^5-9x^2-6x[/tex]
Step-by-step explanation:
[tex]\left(4x^5+8x^5+3x\right)-\left(3x^2+6x^2+9x\right)[/tex]
[tex]4x^5+8x^5+3x-\left(3x^2+6x^2+9x\right)[/tex]
[tex](4x^5+8x^5):12x^5[/tex] ( Combine like terms)
[tex]12x^5+3x-\left(3x^2+6x^2+9x\right)[/tex] (Apply the distributive law)
[tex]12x^5+3x-9x^2-9x[/tex]
[tex](3x-9x):-6x[/tex] ( Combine like terms)
[tex]12x^5-9x^2-6x[/tex]

Answer:
[tex]\sf 9x^2 - 12x^5 +6x[/tex]
solving steps:
[tex]\hookrightarrow \sf (3x^2 + 6x^2 + 9x )- (4x^5 + 8x^5 + 3x)[/tex]
remove parenthesis
[tex]\hookrightarrow \sf 3x^2 + 6x^2 + 9x - 4x^5 - 8x^5 - 3x[/tex]
group variables
[tex]\hookrightarrow \sf 3x^2 + 6x^2 - 4x^5 - 8x^5 - 3x+ 9x[/tex]
simplify
[tex]\hookrightarrow \sf 9x^2 - 12x^5 +6x[/tex]
