\frac{\mathrm{d}}{\mathrm{d}x}(64x^{2}-15)
Add -16 and 1 to get -15.
2\times 64x^{2-1}
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}.
128x^{2-1}
Multiply 2 times 64.
128x^{1}
Subtract 1 from 2.
128x
For any term t, t^{1}=t.
64x^{2}-15
Add -16 and 1 to get -15.
