Step-by-step explanation: The difference between the number of bottles of apple juice sold and the number of bottles of pineapple juice sold will be 14.
The polynomial is subtracted using the distributive property.
.. (16k^3 -3v^4) -(-9k^3 +6v^4)
.. = 16k^3 -3v^4 +9k^3 -6v^4
.. = (16 +9)k^3 +(-3 -6)v^4
.. = 25k^3 -9v^4
"Invert" means different things in different contexts. Here we suppose it means you simply want the reciprocal of this difference:
