Answer 6

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.
