\frac{\mathrm{d}}{\mathrm{d}y}(13y^{2}-4)
Combine 9y^{2} and 4y^{2} to get 13y^{2}.
2\times 13y^{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}.
26y^{2-1}
Multiply 2 times 13.
26y^{1}
Subtract 1 from 2.
26y
For any term t, t^{1}=t.
13y^{2}-4
Combine 9y^{2} and 4y^{2} to get 13y^{2}.
