how do i factor 2d^3+18d.

Here we have to factor the function. 

First see what are the commons in the function. 

In this function "d" is common for both 1st term as well as in the 2nd term.

Let see how "d" is common. 

The function is, 2d^3 + 18d

                         = 2*d*d*d + 18*d

Take one "d" from both term.

                       = d*(2*d*d + 18)

Now there is also another common in this function. That is "2". 

See how 2 is common .

=d*(2*d*d + 2*3*3)

Take 2 from both term.

=d*2*(d*d + 3*3)

Rearranging, 

=2*d(d*d + 3*3)

=2d(d^2 + 9)
