Answer:
2x^2+2x+2
Explanation:
7-7+5x-5x+2+2x^2+2x
ok first off i see 7-7, which is zero so we can leave that out
i also see 5x-5x which is also zero
now we have 2+2x^2+2x left, and to order it properly we put the number with the exponent and variable first, then the number with the variable, and then the number
so your final answer would be
2x^2+2x+2
i hope that helps! if you have any questions just ask!
