Let’s check out your problem:

y=4x^(2)-16 x

y=4x216xy=4x^{2}-16x

Full solution

Q. y=4x216xy=4x^{2}-16x
  1. Identify function: Identify the function to differentiate. y=4x216xy = 4x^2 - 16x
  2. Differentiate terms: Differentiate each term separately using basic power rules.\newlineFor 4x24x^2, the derivative is 8x8x (since ddx\frac{d}{dx} of xn=nxn1x^n = nx^{n-1} where n=2n=2).\newlineFor 16x-16x, the derivative is 16-16 (since ddx\frac{d}{dx} of x=1x = 1).
  3. Combine derivatives: Combine the derivatives of each term. dydx=8x16\frac{dy}{dx} = 8x - 16
