Answer 2

To simplify the given expression, we'll first deal with the absolute value and then perform the necessary algebraic operations. Let's break it down step by step:

1. Dealing with the absolute value (|x|): The absolute value function |x| can be defined as follows: |x| = x, for x >= 0 |x| = -x, for x < 0

2. Replacing the absolute value in the expression: Y = (0.75x^2 + 1.5x) * |x| / (x + 2)

Now, we'll handle the two cases of x: x >= 0 and x < 0

Case 1: x >= 0 When x is non-negative, |x| is equal to x. So, Y = (0.75x^2 + 1.5x) * x / (x + 2)

Case 2: x < 0 When x is negative, |x| is equal to -x. So, Y = (0.75x^2 + 1.5x) * (-x) / (x + 2)

Now, we have two expressions for Y based on the value of x. Let's simplify each expression:

Case 1: x >= 0 Y = (0.75x^2 + 1.5x) * x / (x + 2)

To simplify further, we can cancel out one of the x terms: Y = (0.75x^2 + 1.5x) / (x + 2)

Case 2: x < 0 Y = (0.75x^2 + 1.5x) * (-x) / (x + 2)

Again, simplify by canceling out one of the x terms: Y = -(0.75x^2 + 1.5x) / (x + 2)

So, the simplified expression for Y based on the value of x is as follows:

If x >= 0: Y = (0.75x^2 + 1.5x) / (x + 2)

If x < 0: Y = -(0.75x^2 + 1.5x) / (x + 2)
