log(x) - x^2
Detail solution
  1. Differentiate x2+log(x)- x^{2} + \log{\left(x \right)} term by term:

    1. The derivative of log(x)\log{\left(x \right)} is 1x\frac{1}{x}.

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

      1. Apply the power rule: x2x^{2} goes to 2x2 x

      So, the result is: 2x- 2 x

    The result is: 2x+1x- 2 x + \frac{1}{x}


The answer is:

2x+1x- 2 x + \frac{1}{x}
