Respuesta:

3a+5b+c+5a+b+2c=

=(8a+5b+c)+b+2c=  

=(8a+6b+c)+2c=

=8a+6b+3c

4x-3y-4y+5x-14y-2x=

=(4x−7y)+5x−14y−2x=  

=(9x−7y)−14y−2x=

=(9x−21y)−2x=

=7x−21y

5a+3a2-3a+3b-5a2-7b+8b2=

=(3a2+5a)−3a+3b−5a2−7b+8b2=  

=(3a2+2a+3b)−5a2−7b+8b2=

=(−2a2+2a+3b)−7b+8b2=

=−2a2+2a+8b2−4b

7a+3a2b-3a+3b-5a2b-7b+8b2=

=(3a2b+7a)−3a+3b−5a2b−7b+8b2=

=(3a2b+4a+3b)−5a2b−7b+8b2=

=(−2a2b+4a+3b)−7b+8b2=

=−2a2b+4a+8b2−4b
