Answer 2

To simplify the expression (3,2c-1,8d)-(3,2d+1,2c)+(-2c+1,4d-15+9), you need to perform vector addition and subtraction component-wise:

(3,2c-1,8d) - (3,2d+1,2c) + (-2c+1,4d-15+9)

Now, let's add and subtract the corresponding components:

1. For the x-component: (3 - 3 - 2c + 1) = (0 - 2c + 1) = (-2c + 1)

2. For the y-component: (2c - 2d - 1 + 1) = (2c - 2d)

3. For the z-component: (8d - 2c + 9) - (0) = (8d - 2c + 9)

So, the simplified vector is (-2c + 1, 2c - 2d, 8d - 2c + 9).
