The integral you provided is a bit complex, but let's break it down step by step.

First, notice that the integral is a double integral, which means we need to integrate with respect to y first, then with respect to x. The integral is:

∫ from 1 to 2 ∫ from 0 to 2 (x - x^2) * (x^2 + y^2)^(-1/2) dy dx

Step 1: Integrate with respect to y The inner integral does not depend on y, so we can treat all terms involving x as constants. The integral of a constant with respect to y is simply the constant times y. Therefore, the inner integral simplifies to:

(x - x^2) * y * (x^2 + y^2)^(-1/2) evaluated from y=0 to y=2

Step 2: Evaluate the inner integral Substitute y=2 and y=0 into the expression obtained in step 1. The term involving y=0 will vanish because it is multiplied by y. The term involving y=2 becomes:

2 * (x - x^2) * (x^2 + 4)^(-1/2)

Step 3: Integrate with respect to x Now we need to integrate the expression obtained in step 2 with respect to x, from x=1 to x=2. This is a bit more complicated and requires techniques such as substitution or integration by parts.

Unfortunately, the integral does not seem to simplify to any of the provided answer choices. It's possible that there may be a mistake in the problem statement or the answer choices.
