Terms & Factors of an Expression
Suppose we have an expression
Here,
The terms are 2x & −3
& factors of 2 are 2, x
Here, −3 is a constant
For 4x ^{ 3 } − 9xyz
The terms are 4x ^{ 3 } and −9xyz
and factors of 4x ^{ 3 } are 4, x, x and x
and factors of −9xyz are −9 , x, y, z
25x + y
The terms are 25x + y
and factors of 25x are 25 and x
factors of y is y
15xy − 25y + 18
The terms are 15xy, –25y and 18
and factors of 15xy are 15, x and y,
factors of −25y are −25 and y
Here, 18 is a constant
The above tree formed to find terms & factors is called a tree diagram
We can also find terms & factors using table
