### Instruction: What is \[2-4x-6x^2+8+10x-12x^2-14+16x+18x^2\] in terms of $x$?### Response: This is a polynomial expression, so I can simplify it by combining like terms.
The like terms are the constant terms, the terms with $x$, and the terms with $x^2$.
For the constant terms, I have $2+8-14= -4$.
For the terms with $x$, I have $-4x+10x+16x=22x$.
For the terms with $x^2$, I have $-6x^2-12x^2+18x^2=0$.
