A subtraction can be written as an addition of the opposite.
In general,
a - b = a + (-b)
Example:
5x - 3y = 5x + (-3y)
A polynomial is a SUM of terms.
If a polynomial shows the terms being subtracted, rewrite the subtractions as additions of the opposite, and that shows the terms.
Example:
What are the terms of the following polynomial?
\(2x^3 - 3x^2 + 4x - 7\)
Solution.
We rewrite the polynomial showing the sum of the terms:
\(2x^3 + (-3x^2) + 4x + (-7)\)
The terms are: \(2x^3,~-3x^2, ~4x, ~-7\)
What this question is doing is to make sure you understand that each term includes the minus sign to its left.
