What is the result of adding -3X exponent 2 - 5x + 1 from 8x-2X-9

Given the expressions:
[tex]-3X^2-5X+1\text{ and 8}X^2-2X-9[/tex]Let's add both expressions.
First set up the addition expression:
[tex](-3X^2-5X+1)+(8X^2-2X-9)[/tex]Remove the parentheses and combine like terms:
[tex]\begin{gathered} -3X^2+8X^2-5X-2X+1-9 \\ \\ =5X^2-7X-8 \end{gathered}[/tex]Therefore, the result of adding both expressions is:
