(9w-4w^2 + 10) + (8w^2 + 7 + 5w)
9w - 4w^2 + 10 + 8w^2 + 7 + 5w
addition is commutative, so
-4w^2 + 8w^2 + 9w + 5w + 10 + 7
multiplication distributes, so
(-4+8)w^2 + (9+5)w + (10+7)
4w^2 + 14w + 17
degree is the highest power of x
terms are separated by + or - signs
Simplify and write in standard form. Then, classify
the polynomial by degree and number of terms.
(9w-4w^2 + 10) + (8w^2 + 7 + 5w)
