As the left number increases by 1, the right number increases by 4. So as you can see, the left numbers go 3-4-5 while the right numbers go 12-16-20. So the answer is 10:40 because 10x4=40.
For this case we have the following polynomials: By subtracting both polynomials we have: What we must do is subtract terms of the same degree. We have then: Answer: will be a polynomial
will be a polynomial
