Question

1)Some os termos semelhantes a)2x+3x b)6xy-4y+5y c)3a-6a-a d)2x+x-3x e)2/5m+3/2m f)1/2ab-3ab

Answer 1

1) 

a)
2x + 3x = 0
5x = 0

b)
6xy - 4y + 5y = 0
6xy + y = 0

c)
3a - 6a - a = 0
3a - 7a = 0
- 4a = 0

d)
2x + x - 3x = 0
3x - 3x = 0
0 = 0

e) 
$\frac{2}{5}m$ + $\frac{3}{2}m$ = 0
$\frac{4 + 15}{10}m$ = 0
$\frac{19}{10}m$ = 0

f) 
$\frac{1}{2}ab$ - 3ab = 0
$\frac{1 - 6}{2}ab$ = 0
$-\frac{5}{2}ab$ = 0
