Answer:

2x^3 - 2x^2 - 9x + 3

Explanation:

(2x^3 − 3x + 2) - (2x^2 + 6x − 1) =

2x^3 − 3x + 2 - 2x^2 + (-6x) − (-1) = ==> distribute the negative sign to 2x^2,

6x, and -1 in (2x^2 + 6x − 1)

Adding a negative number is equivalent to subtracting by a positive number.

Subtracting a negative number is equivalent to adding by a positive number.

Hence:

2x^3 − 3x + 2 - 2x^2 - 6x + 1 =

2x^3 - 2x^2 - 3x - 6x + 2 + 1 = ==> rearrange the expression in which like

terms are matching

2x^3 - 2x^2 - 9x + 3 ==> simplify
