Answer:

When numbers are added or subtracted they are called terms

Step-by-step explanation:

1.example 5x3-4x3 +9x-8.

The variable in this case x, also called the argument of the polynomial here is a polynomial argument t

T2-5t +1

2.a variable is a symbol that takes on different values A value is a number.

Thus if x is a variable and we give it the value 4 then 5xt1 has the value 21.
