2 (x + 2)
d / 2\ --\(x + 2) / dx
Let u=x+2u = x + 2u=x+2.
Apply the power rule: u2u^{2}u2 goes to 2u2 u2u
Then, apply the chain rule. Multiply by ddx(x+2)\frac{d}{d x} \left(x + 2\right)dxd(x+2):
Differentiate x+2x + 2x+2 term by term:
Apply the power rule: xxx goes to 111
The derivative of the constant 222 is zero.
The result is: 111
The result of the chain rule is:
The answer is:
4 + 2*x
