8ab + 3bc - 12 is an expression. It is neither an equation nor an inequality and, therefore, there can be no answer.
-5ab + 7ab -9ab + ab -2ab ... Let's simplify that a bit:ab(-5+7-9+1-2) = -8ab
There's no answer, because that's not a problem or a question. There would be a question there if that expression were equal to something. But so far, it's just an expression; it doesn't make any statement yet. Were you asked to 'factor' it ? OK. It's equal to 2a (3a - 4b + 1) . But that's just a different way to write the same thing. Nothing has changed, there's no new information, and it doesn't answer any question.
8ab/4c^7=2ab/c^7
6a to the second power minus 8ab + 2a
6a squared-8ab+2a factor completely and check mentally
6a2 - 8ab + 2aas you can see a is common to all terms. And 2 is a factor of 6,8, and 2. So 2a is a factor of all three terms:2a(3a-4b+1)
To factorize the expression 7a^2 - 8ab, you need to find the greatest common factor of the two terms. In this case, the common factor is a. So, you can factor out an 'a' to get a(7a - 8b) as the factored form of the expression. This means that 7a^2 - 8ab can be simplified as a multiplied by the quantity (7a - 8b).
2a(3a - 4b + 1)
Provided multiplication is commutative, it is 8ab.
That factors to 4(a - b)(a + 3b)
8ab + 3bc - 12 is an expression. It is neither an equation nor an inequality and, therefore, there can be no answer.
-5ab + 7ab -9ab + ab -2ab ... Let's simplify that a bit:ab(-5+7-9+1-2) = -8ab
8ab
it means that to do sex with girl
Oh, isn't that a beautiful mathematical expression you have there? When we simplify it, we can see that 3ab and 5ba are actually the same thing! Both expressions represent the product of 3 and a, and b. Just like painting a happy little tree, sometimes math can surprise us with its simplicity and beauty.
