Simplify the following:
a^2+7 a+12-16/a^2
Put each term in a^2+7 a+12-16/a^2 over the common denominator a^2: a^2+7 a+12-16/a^2 = a^4/a^2+(7 a^3)/a^2+(12 a^2)/a^2-16/a^2:
a^4/a^2+(7 a^3)/a^2+(12 a^2)/a^2-16/a^2
a^4/a^2+(7 a^3)/a^2+(12 a^2)/a^2-16/a^2 = (a^4+7 a^3+12 a^2-16)/a^2:
Answer: |
| (a^4+7 a^3+12 a^2-16)/a^2
