Detail solution
  1. Let u=x7u = x - 7.

  2. Apply the power rule: u2u^{2} goes to 2u2 u

  3. Then, apply the chain rule. Multiply by ddx(x7)\frac{d}{d x} \left(x - 7\right):

    1. Differentiate x7x - 7 term by term:

      1. Apply the power rule: xx goes to 11

      2. The derivative of the constant (1)7\left(-1\right) 7 is zero.

      The result is: 11

    The result of the chain rule is:

    2x142 x - 14


The answer is:

2x142 x - 14
