2 (x - 6)
(x - 6)^2
Let u=x−6u = x - 6u=x−6.
Apply the power rule: u2u^{2}u2 goes to 2u2 u2u
Then, apply the chain rule. Multiply by ddx(x−6)\frac{d}{d x} \left(x - 6\right)dxd(x−6):
Differentiate x−6x - 6x−6 term by term:
Apply the power rule: xxx goes to 111
The derivative of the constant −6-6−6 is zero.
The result is: 111
The result of the chain rule is:
The answer is:
-12 + 2*x
