Derivative of 2x^2-5x+3

1. Differentiate $\left(2 x^{2} - 5 x\right) + 3$ term by term:

   1. Differentiate $2 x^{2} - 5 x$ 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: $x^{2}$ goes to $2 x$

         So, the result is: $4 x$

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

         1. Apply the power rule: $x$ goes to $1$

         So, the result is: $-5$

      The result is: $4 x - 5$

   2. The derivative of the constant $3$ is zero.

   The result is: $4 x - 5$

The answer is:
