Explanation:
Given,
-4/x^2
Rewrite the expression using
d/(dx)(-4/x^2)
Break down the fraction.
=d/(dx)(-4*1/x^2)
Using the multiplication by a constant rule,
=-4*d/(dx)(1/x^2)
Rewrite
=-4*d/(dx)(x^-2)
Using the power rule,
=-4*-2x^(-2-1)
Simplify.
=color(green)(|bar(ul(color(white)(a/a)color(black)(8x^-3)color(white)(a/a)|)))
