2 (x + 3)
d / 2\ --\(x + 3) / dx
Let u=x+3u = x + 3u=x+3.
Apply the power rule: u2u^{2}u2 goes to 2u2 u2u
Then, apply the chain rule. Multiply by ddx(x+3)\frac{d}{d x} \left(x + 3\right)dxd(x+3):
Differentiate x+3x + 3x+3 term by term:
Apply the power rule: xxx goes to 111
The derivative of the constant 333 is zero.
The result is: 111
The result of the chain rule is:
The answer is:
6 + 2*x
