1)) Simplify.Express your answer as a single fraction in simplest form. (3d)/(d+2)-(3d-4) square

To simplify the expression $\frac{3d}{d+2} - (3d - 4)$, we need to combine the terms into a single fraction.

First, rewrite the expression:
$$\frac{3d}{d+2} - (3d - 4)$$

Next, find a common denominator for the terms. The common denominator is $d+2$.

Rewrite the second term with the common denominator:
$$\frac{3d}{d+2} - \frac{(3d - 4)(d+2)}{d+2}$$

Now, distribute in the numerator of the second term:
$$\frac{3d}{d+2} - \frac{3d(d+2) - 4(d+2)}{d+2}$$

Simplify the numerator of the second term:
$$3d(d+2) - 4(d+2) = 3d^2 + 6d - 4d - 8 = 3d^2 + 2d - 8$$

So the expression becomes:
$$\frac{3d}{d+2} - \frac{3d^2 + 2d - 8}{d+2}$$

Combine the fractions over the common denominator:
$$\frac{3d - (3d^2 + 2d - 8)}{d+2}$$

Simplify the numerator:
$$3d - 3d^2 - 2d + 8 = -3d^2 + d + 8$$

Thus, the simplified expression is:
$$\frac{-3d^2 + d + 8}{d+2}$$

Therefore, the final answer is:
$$\boxed{\frac{-3d^2 + d + 8}{d+2}}$$
