Question

Reduceti termeni asemenea:
a)8x+5x b)-6m-8m c)5a-7b-6a+b d)5a+3a
e)9a-3b+a-8a+5b
f)8x/3-8x/2+8x+8x/2-8x
Aduceti la forma mai simpla:
a/3+2a+2+7a
2a/3-4a/2-5a/2-a/3+a-3-a

Answer 1

a)8x+5x=13x 
b)-6m-8m=-14m
 c)5a-7b-6a+b =5a-6a-7b+b=-a-b
d)5a+3a=8a
e)9a-3b+a-8a+5b=9a+a-8a-3b+5b=2a+2b=2(a+b)
f)8x/3-8x/2+8x+8x/2-8x=8x/3
Aduceti la forma mai simpla:
a/3+2a+2+7a=5+9a
2a/3-4a/2-5a/2-a/3+a-3-a=2a/3-a/3-4a/2-5a/2-3=a/3--9a/2-3=(2a-18a-18)/6=
(-16a-18)/6=-2(8a-9)/6=(-8a-9)/6
