What is 12 times b squared minus 8 times b equals 0?
12b2 - 8b = 0 4b(3b-2) = 0 4b = 0 and 3b-2 = 0 4b = 0 and 3b = 2 b = 0 and 2/3
4 x b-1 plus -4 plus 4b?
Well if it is worded right then 4xb-1+(-4)+4b=4b-1-4+4b=4b+4b-1-4=8b-5
B to the 3rd power minus 25b squared minus 4b plus 100?
b^3 - 25b^2 - 4b + 100 = 0 b = 25 or b = -2
What is 3a plus 5b minus 6a minus 9b?
3a + 5b - 6a - 9b = -3a - 4b
How do you solve 5b squared equals 8b?
5b2 = 8b therefore 5b =8 therefore b = 1.6
What is 8b-4b?
12
What is the answer of 8b plus 4b 56 - 16b what is the value of b?
If you mean 8b+4b = 56-16b then the value of b works out as 2
3a 4b equals 7a 4b?
Clearly, there are some signs missing. So let's try the four possibilities for the second terms: 1. + and + 3a + 4b = 7a + 4b Subtract 4b from each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 2. + and - 3a + 4b = 7a - 4b Subtract 4b from each side: 3a = 7a - 8b Subtract 7a from each side: -4a = -8b or 4a = 8b Answer: a = 2b 3. - and - 3a - 4b = 7a - 4b Add 4b to each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 4. - and + 3a - 4b = 7a + 4b Add 4b to each side: 3a = 7a + 8b Subtract 7a from each side: -4a = 8b or 4a = -8b Answer: a = -2b Can't do better than that with the information available.
How do you factor 2a plus 8b?
2(a + 4b)
What is 12 times b squared minus 8 times b equals 0?
12b2 - 8b = 0 4b(3b-2) = 0 4b = 0 and 3b-2 = 0 4b = 0 and 3b = 2 b = 0 and 2/3
4 x b-1 plus -4 plus 4b?
Well if it is worded right then 4xb-1+(-4)+4b=4b-1-4+4b=4b+4b-1-4=8b-5
What is the answer to the math equation 2bc plus 8b minus 3c minus 12?
2bc + 8b - 3c - 12 is an expression, not an equation or inequality. It cannot, therefore have "an answer".
What is 4b minus 2c?
4b - 2c is an expression, which is equal to 2(2b - c)
B to the 3rd power minus 25b squared minus 4b plus 100?
b^3 - 25b^2 - 4b + 100 = 0 b = 25 or b = -2
Negative parenthesis 3a plus 7b parenthesis minus 8a minus 4b plus 2?
Numerically, if the question looks like this:--(3a + 7b) - 8a - 4b + 2Then the answer is this:--3a - 7b - 8a - 4b + 2= -11a -11b + 2
How do you solve b squared minus 8b plus 16?
(b-4) squared
What is 3a plus 5b minus 6a minus 9b?
3a + 5b - 6a - 9b = -3a - 4b
