We have to substract an expression from another. We can write this as:
[tex]\mleft(-17x^2-5x+3\mright)-(-9x^2+7x+13)[/tex]We can simplify this as:
[tex]\begin{gathered} (-17x^2-5x+3)-(-9x^2+7x+13) \\ -17x^2-5x+3+9x^2-7x-13 \\ (-17+9)x^2+(-5-7)x+(3-13) \\ -8x^2-13x-10 \end{gathered}[/tex]Answer: if we substract these two expressions, we get -8x^2-13x-10.
