Given the expression below
[tex](6x^5-2x^3+x^2+5x)-(8x^5+2x^3-11x^2+9)[/tex]
Expanding the expression and simplifying them by multiplying the second expression by the negative(-) sign.
[tex]\begin{gathered} 6x^5-2x^3+x^2+5x-8x^5-2x^3+11x^2-9 \\ 6x^5-8x^5-2x^3-2x^3+x^2+11x^2+5x-9 \\ -2x^5-4x^3+12x^2+5x-9 \end{gathered}[/tex]
Hence, the answer is
[tex]-2x^5-4x^3+12x^2+5x-9[/tex]
