Need help with this what to do with minus symbol between parenthesis

Answer 1

Given the expression below

`(6x^5-2x^3+x^2+5x)-(8x^5+2x^3-11x^2+9)`

Expanding the expression and simplifying them by multiplying the second expression by the negative(-) sign.

`\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}`

Hence, the answer is

`-2x^5-4x^3+12x^2+5x-9`
