\frac{\mathrm{d}}{\mathrm{d}x}(3x^{2}+8x+20)
Multiply 4 and 5 to get 20.
2\times 3x^{2-1}+8x^{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}.
6x^{2-1}+8x^{1-1}
Multiply 2 times 3.
6x^{1}+8x^{1-1}
Subtract 1 from 2.
6x^{1}+8x^{0}
Subtract 1 from 1.
6x+8x^{0}
For any term t, t^{1}=t.
6x+8\times 1
For any term t except 0, t^{0}=1.
6x+8
For any term t, t\times 1=t and 1t=t.
3x^{2}+8x+20
Multiply 4 and 5 to get 20.
