\frac{\mathrm{d}}{\mathrm{d}K}(-11K+4)
Combine K and -12K to get -11K.
-11K^{1-1}
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}.
-11K^{0}
Subtract 1 from 1.
-11
For any term t except 0, t^{0}=1.
-11K+4
Combine K and -12K to get -11K.
