Question

Consider the expression 8ab + 3b - 16 - 4a. RE (a) How many terms are there? (b) How many factors are in the first term? Identify them. (c) Which term is a constant?

Answer 1

• 4 terms

,

• 3 factors, 8,a, and b

,

• -16

1) Considering the expression 8ab +3b-16-4a

a) Note that we can see that there are four terms namely:

`8ab,3b,-16,-4a`

b) In the first term we can see three factors note that factors are also known as the multiplier and the multiplicand for this so:

`8ab=8\cdot a\cdot b`

So, there are three terms

c) Constant terms are the terms that do not have any dependent term on x, in other words, the constant here is -16
