[9x2+10x+4]-[9x2+5x-1]
9x2-9x2 gone
10x-5x=5x
4-[-1]=5
ans=5x+5 opt a

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
