For this case we have the following polynomials:
[tex](9x ^ 2 + 10x + 4)
(9x ^ 2 + 5x - 1)
[/tex]
Subtracting both polynomials we have:
[tex](9x ^ 2 + 10x + 4) - (9x ^ 2 + 5x - 1)
[/tex]
We group terms with the same exponent:
[tex](9x ^ 2 - 9x ^ 2) + (10x - 5x) + (4 - (-1))
[/tex]
Rewriting we have:
[tex](9x ^ 2 - 9x ^ 2) + (10x - 5x) + (4 +1)
5x + 5[/tex]
Answer:
The difference is given by:
(a) 5x + 5
