The derivative of x squared is 2x. The derivative with respect to x of pi of a constant is just 0. The derivative with respect to x of 1 is just a constant. It's just 0. So once again, this is just going to be equal to 2x. In general, the derivative with respect to x of x squared plus any constant is going to be equal to 2x. The derivative of x squared with respect to x is 2x.
