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
