3b+6b=9b
add like terms: 3a -2a -5b + 6b +3b - 7b = a -3b
6+7a+6b
It is 17b when simplified
12a + 6b + 6c = 6(2a + b + c)
3b+6b=9b
6(b - ac + b2 - bc)
add like terms: 3a -2a -5b + 6b +3b - 7b = a -3b
6(ab - ac + b2 - bc)
5b - 3 - 2b = 6b - 3 3b - 3 = 6b - 3 3b - 6b = 3 - 3 b = 0
2a+2b+3a+3b+a+b= 6a+6b 2a+3a+a=6a 2b+3b+b=6b
7 + 4b + 3b + 6b + 5 =7 + 13b + 5 =12 + 13b
6+7a+6b
b3 - 5b2 + 12 = (b - 2)(b2 - 3b - 6)Check:(b - 2)(b2 - 3b - 6)= b(b2 - 3b - 6) - 2(b2 - 3b - 6)= b3 - 3b2 - 6b - 2b2 + 6b + 12= b3 - 5b2 + 12
3b-4-6b-5
It is 17b when simplified
