Solve 3-a-2^2

$$3 - a - 2 ^ { 2 }$$

Evaluate

$$-a-1$$

Solution Steps

Calculate 2 to the power of 2 and get 4.

$$3-a-4$$

Subtract 4 from 3 to get -1.

$$-1-a$$

Differentiate w.r.t. a

$$-1$$

Steps Using Derivative Rule for Sum

Calculate 2 to the power of 2 and get 4.

$$\frac{\mathrm{d}}{\mathrm{d}a}(3-a-4)$$

Subtract 4 from 3 to get -1.

$$\frac{\mathrm{d}}{\mathrm{d}a}(-1-a)$$

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}.

$$-a^{1-1}$$

Subtract 1 from 1.

$$-a^{0}$$

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

$$-1$$
