DaniilM [7]

Answer:

sum of the polynomials is 9 x^{3} - 4 x^{2} +3x

hundreds tens ones. tenths hundredths  

1                   5   6      .     3         2

The three is in the tenths place.  We want a number that is 10 times this 3.  So it needs to be in the ones place.

.3 * 10 = 3

So any number with a 3 in the ones place is valid.
