log(2*x^2 - 3*x + 6)
Detail solution
  1. Let u=(2x23x)+6u = \left(2 x^{2} - 3 x\right) + 6.

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

  3. Then, apply the chain rule. Multiply by ddx((2x23x)+6)\frac{d}{d x} \left(\left(2 x^{2} - 3 x\right) + 6\right):

    1. Differentiate (2x23x)+6\left(2 x^{2} - 3 x\right) + 6 term by term:

      1. Differentiate 2x23x2 x^{2} - 3 x term by term:

        1. 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: 4x4 x

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

          1. Apply the power rule: xx goes to 11

          So, the result is: 3-3

        The result is: 4x34 x - 3

      2. The derivative of the constant 66 is zero.

      The result is: 4x34 x - 3

    The result of the chain rule is:

    4x3(2x23x)+6\frac{4 x - 3}{\left(2 x^{2} - 3 x\right) + 6}

  4. Now simplify:

    4x32x23x+6\frac{4 x - 3}{2 x^{2} - 3 x + 6}


The answer is:

4x32x23x+6\frac{4 x - 3}{2 x^{2} - 3 x + 6}
