Now, next of exercise, 23.
00:03
In this exercise, we want to find the derivative of the function.
00:08
Fx equals 2x cubed minus 4x squared plus 3 over x.
00:24
We can rewrite this expression as 2x cubed minus 4x plus 3 over x.
00:35
X and we can still rewrite it as since 3 over x just equals 3 times x to a power of minus 1.
00:50
And now according to rule 4, the derivative of the sum equals the sum of derivative.
01:00
Hence is just the sum of the derivative of the first term plus the derivative of the second term plus the derivative of the second term plus the the derivative of a third term.
01:25
To find the derivative of the first term, let's use rule 3.
01:31
It equals the constant times a derivative of x squared.
01:37
And now here comes the root 2...
