Subtract the same kind together. what I meant by "same kind" is 
$$8.3x ^{2} - 7.4 x ^{2}$$
and subtract xy terms together, and subtract number together.
your final answer should contain three terms.

0.9

ghostfire · Answer

almost, it's $$0.9x^{2}$$

anonymous · Answer

how do you get the factored answer

ghostfire · Answer

then the second portion of the answer is 
0.9xy-(-1.7xy)
the third portion of the answer is
3.6-6.4

ghostfire · Answer

common mistake is combined different terms together. i.e 
$$5x^{2}-2xy \neq 3xy$$  (you can't subtract or add x^2 to xy, but you can multiply and divide)
