Answer 1

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.

Answer 2

0.9

Answer 3

almost, it's \[0.9x^{2}\]

Answer 4

how do you get the factored answer

Answer 5

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

Answer 6

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)
