Answer:
 A) 2x^2 -12x +13
 B) terms {2x^2, -12x, 13}; coefficients {2, -12, 13}; constants {13}
Step-by-step explanation:
A) Using the distributive property, we get ...
 -2x +3 +2x^2 -10x +10
 = 2x^2 -12x +13
__
B) Terms: {2x^2, -12x, 13}
 Factors: There are no overall factors. Each term has factors ...
   2x^2 has factors {2, x, x}
   -12x has factors {-1, 2, 2, 3, x}
   13 has factors {1, 13} (it is prime)
 Coefficients: {2, -12, 13} . . . see note below
 Constants: {13}
_____
Additional comment
We have listed the prime factors of each term, any subset can be multiplied to be a factor of the term. For example, 2·3 = 6 is a factor of -12x.
Please note that some sources do not consider a constant (13) to be a coefficient. You will need to refer to your curriculum materials to see what your author says about that.
