4b^2
(5a - 4b) + (2c - 3b - 6c) + a =5a - 4b + 2c - 3b - 6c + a =(5a + a) + (-4b - 3b) + (2c - 6c) =[ 6a - 7b - 4c ].
18h+4b-2b
4b - 9 + 2b + 8 Coefficients are the numbers in front of the variables. Therefore the coefficient of 4b is 4 and the coefficient of 2b is 2. The like terms are 2b and 2b, but also -9 and 8. Constant terms are the ones that do not contain a variable. -9 and 8 are the constants. 4b - 9 + 2b + 8 can be simplified (by combining like terms) to give 2b - 1
4b-b
4b^2
(5a - 4b) + (2c - 3b - 6c) + a =5a - 4b + 2c - 3b - 6c + a =(5a + a) + (-4b - 3b) + (2c - 6c) =[ 6a - 7b - 4c ].
-2b+8-4b = -5-11b+7 -2b-4b+11b = -5+7-8 5b = -6 b = -6/5
LCM(2b, 6c) = 6bc.
2B 2B or not 2B, that is the question.
18h+4b-2b
2B or not 2B, that is the question.
The simplified answer is: 4c+2b
c-2b
I ask my 11 year old son. 2b + 18 = 4b Subtract 2b form each side: 18 = 2b Divide each side by 2: 9 = b which is the same as b = 9, but you knew that, didn't you?
4b - 9 + 2b + 8 Coefficients are the numbers in front of the variables. Therefore the coefficient of 4b is 4 and the coefficient of 2b is 2. The like terms are 2b and 2b, but also -9 and 8. Constant terms are the ones that do not contain a variable. -9 and 8 are the constants. 4b - 9 + 2b + 8 can be simplified (by combining like terms) to give 2b - 1
