Final answer:

To divide (3x^2 - 5x - 2) by (x - 2) using long division, we would get a quotient of 3x + 1 after performing the standard division steps including dividing, multiplying, and subtracting until all terms are accounted for.

Step-by-step explanation:

To find the quotient of (3x^2 - 5x - 2) divided by (x - 2) using long division, follow these steps:

  1. Divide the first term of the numerator by the first term of the denominator: 3x^2 divided by x is 3x.
  2. Multiply the entire denominator by this result (3x) and subtract it from the numerator.
  3. Bring down the next term from the numerator and repeat the process until all terms are accounted for.

The expected result would be one of the answer options provided: a) 2x - 1, b) 2x + 1, c) 3x - 1, or d) 3x + 1.

When we carry out the division, we get 3x for the first term of the quotient. Multiplying (x - 2) by 3x gives us 3x^2 - 6x, which we subtract from 3x^2 - 5x. This leaves us with x. Dividing x by x gives 1, and the process ends as there are no more terms to bring down.

The final quotient is 3x + 1.
