Explanation:
To simplify we expand the brackets (distribute ). This is referred to as the
#color(blue)"distributive law"# To do this multiply each 'term' inside the bracket by 2h, remembering the rule of 'signs' when multiplying terms together.
#rArrcolor(red)"2h"(-7h^2-4h)#
#=color(red)"2h"xx(-7h^2)-color(red)"2h"xx4h=-14h^3-8h^2#
