The derivative with respect to x of 2x-4x+5 is the sum of the derivative of each term. Therefore d (2x-4x+5)/dx = d 2x/dx +d (-4x)/dx + d(5)/dx = 2-4+0 = -2 Since d 2x/dx = 2 dx/dx = 2; d(-4x)/dx =-4 (dx/dx) = -4; and the derivative of a constant is zero.

You may mean 2x^2 - 4x + 5, but I'll answer both.
2x^2 - 4x + 5
derivative: 4x - 4
2x - 4x + 5 = -2x + 5
derivative: -2

with respect to what variable?
d/dx (2x-4x+5) is -2
However, that's an awkward way of writing the problem. Perhaps you meant 2x² - 4x +5
then d/dx is 4x -4

Add the terms together...
2x - 4x = -2x
the five stays where it is.
So you have -2x + 5
So the derivative of this is -2.
