3a+6b are two terms of an expression
12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
6b+b+b is the same as 6b+1b+1b you can add the numbers together if the variables are the same. 6b+1b+1b=8b
The answer to 6b plus 7 times 5-4b plus 1 equals 38. This is taught in math.

3a+6b are two terms of an expression
add like terms: 3a -2a -5b + 6b +3b - 7b = a -3b
Change the order to make it more obvious: 3a - a + 2b + 4b 2a + 6b or 2 (a + 3b).
2a+2b+3a+3b+a+b= 6a+6b 2a+3a+a=6a 2b+3b+b=6b
3(-2b3pa)
11b + 6b = 17b
12a + 6b + 9a + 14b =(12a + 9a) + (6b + 14b) =21a + 20b
6b+b+b is the same as 6b+1b+1b you can add the numbers together if the variables are the same. 6b+1b+1b=8b
6(a+b)
The polynomial IS b2 - 6b + 8.
The answer to 6b plus 7 times 5-4b plus 1 equals 38. This is taught in math.
