F.1 Maths!!!!!!!!!!!!!極急!!!!!!!!!!!!!!

a) no. of term →2
b) constant terms →1

a)4
b)1

7b+18-5b-8/b
=7b-5b+18-8/b
=2b+18-8/b
so a)according to the answer,the answer have 3 terms,the constant term=18

7b+18-5b-8/b
=7b-5b+18-8/b
=2b+18-8/b
a)according to the answer,the answer have 3 terms,the constant term=18

a) 7b-5b=2b is one of the term
18 is one term
-8/b is one term
SO, 3 terms
b) 18

7b+18-5b-8/b
=18+2b-8/b
a) no. of term =3
b) constant terms =18

我的理解是 no. of constant terms=1 lor

13b+18-8/b
