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)|)))#
