2 (x - 5)
(x - 5)^2
Let u=x−5u = x - 5u=x−5.
Apply the power rule: u2u^{2}u2 goes to 2u2 u2u
Then, apply the chain rule. Multiply by ddx(x−5)\frac{d}{d x} \left(x - 5\right)dxd(x−5):
Differentiate x−5x - 5x−5 term by term:
Apply the power rule: xxx goes to 111
The derivative of the constant −5-5−5 is zero.
The result is: 111
The result of the chain rule is:
The answer is:
-10 + 2*x
