    ok, this is just combining like terms if 10 - 8 = 2, then what is 10c^3 - 8c^3 = ?

    4. Find the difference. (9a^4 + 2a^2 + 5) - (16a^4 - 7a^2 + 1) A) 25a^4 - 5a^2 - 4 B) -7a^4 - 5a^2 + 6 C) 25a^8 + 9a^4 + 6 D) -7a^4 + 9a^2 + 4

    good! so, any ideas on what 9a^4 - 16a^4? (remember, when we add/subtract terms with exponents, the exponents don't change)

    -7a^-4 + 9a^2 + 4
