#24x^2 - 46xy + 21y^2#

#6x * 4x = 24x^2#

#6x * -3y = -18xy#

#-7y * 4x = -28xy#

#-7y * -3y = 21y^2#

When we combine it all together we get:
#24x^2 - 18xy - 28xy + 21y^2#

We can still simplify this because #-18xy# and #-28xy# are like terms:
#-18xy - 28xy = -46xy#

So the final simplified answer is:
#24x^2 - 46xy + 21y^2#

Hope this helps!
