x+x- \sqrt{x} + x
x - sqrt(x)
Detail solution
  1. Differentiate x+x- \sqrt{x} + x term by term:

    1. Apply the power rule: xx goes to 11

    2. The derivative of a constant times a function is the constant times the derivative of the function.

      1. Apply the power rule: x\sqrt{x} goes to 12x\frac{1}{2 \sqrt{x}}

      So, the result is: 12x- \frac{1}{2 \sqrt{x}}

    The result is: 112x1 - \frac{1}{2 \sqrt{x}}


The answer is:

112x1 - \frac{1}{2 \sqrt{x}}
