2*x - 1 (x - 4)*e
d / 2*x - 1\ --\(x - 4)*e / dx
Apply the product rule:
; to find :
Differentiate term by term:
Apply the power rule: goes to
The derivative of the constant is zero.
The result is:
; to find :
Let .
The derivative of is itself.
Then, apply the chain rule. Multiply by :
Differentiate term by term:
The derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: goes to
So, the result is:
The derivative of the constant is zero.
The result is:
The result of the chain rule is:
The result is:
Now simplify:
The answer is:
2*x - 1 2*x - 1 e + 2*(x - 4)*e
