$$-4,9-2,5d-2$$

Subtract 2 from -4,9 to get -6,9.

$$-6,9-2,5d$$

Differentiate w.r.t. d

$$-2,5$$

Steps Using Derivative Rule for Sum

Subtract 3,5 from -1,4 to get -4,9.

$$\frac{\mathrm{d}}{\mathrm{d}d}(-4,9-2,5d-2)$$

Subtract 2 from -4,9 to get -6,9.

$$\frac{\mathrm{d}}{\mathrm{d}d}(-6,9-2,5d)$$

The derivative of a polynomial is the sum of the derivatives of its terms. The derivative of a constant term is 0. The derivative of ax^{n} is nax^{n-1}.

$$-2,5d^{1-1}$$

Subtract 1 from 1.

$$-2,5d^{0}$$

For any term t except 0, t^{0}=1.

$$-2,5$$
