Explanation:
#"differentiate using the "color(blue)"power rule"#
#•color(white)(x)d/dx(ax^n)=nax^(n-1)#
#dy/dx=8x^3-6x^2-0=8x^3-6x^2#

Explanation:
The key to differentiating polynomials is using the Power Rule. Here, the coefficient comes out front, and the exponent gets decremented by one. Here's how this looks mathematically:
Also recall that the derivative of a constant is zero. Applying this, we get
