Plug in #h=-2# for the expression #(4(3h-6))/(1+h)#.

When #h=-2#,

#:.=(4(3*-2-6))/(1+(-2)#

#=(4(-6-6))/-1#

#=(4*-12)/-1#

#=(-48)/-1#

#=48#

#48#

#"substitute h = - 2 into the expression"#

#rArr(4((3xxcolor(red)(-2))-6))/(1+color(red)(-2))#

#=(4(-6-6))/(1-2)#

#=(4xx-12)/(-1)=(-48)/(-1)=48#
