#2d^2+6d-7#

#5d^2+4d-3-(3d^2-2d+4)#

#=5d^2+4d-3+ -(3d^2-2d+4)#

#=5d^2+4d-3-3d^2+2d-4#

collect like terms:

#5d^2-3d^2+4d+2d-3-4#

#=2d^2+6d-7#

Same thing. Different format.
Assumption: the word 'less' is taken to mean subtract (remove)

#2d^2+6d-7#

#5d^2+4d-3#
#ul(3d^2-2d+4larr" Subtract")#
#2d^2+6d-7#
