Question

-12a^2-6bc+9ac-8ab решите пж

Answer 1

С учётом исправленного задания :
12a² - 6bc + 9ac - 8ab = (12a² + 9ac) - (6bc + 8ab) = 3a(4a+3c) - 2b(3c + 4a) =
= (4a + 3c)(3a - 2b)

Answer 2

-12a^2-6bc+9ac+8ab=-3a(4a-3c)+2b(4a-3c)=(4a-3c)(2b-3a)

Answer 3

To solve the expression, it seems like you want to factor it. However, the expression you provided is not an equation, so there's nothing to solve for in the traditional sense. Instead, I can help you factor the expression if that's what you're looking for.

The expression you provided is: -12a^2 - 6bc + 9ac - 8ab

To factor it, let's look for common terms and then try to factor out those common terms:

Step 1: Factor out the common term 'a' from the first two terms: -12a^2 - 8ab

Common term: 'a' Factor: a(-12a - 8b)

Step 2: Factor out the common term 'c' from the middle two terms: -6bc + 9ac

Common term: 'c' Factor: c(-6b + 9a)

Now, we have the factored expression: -12a^2 - 6bc + 9ac - 8ab = a(-12a - 8b) + c(-6b + 9a)

The expression is now in factored form. If you have any other specific instructions or if there's something else you'd like to do with this expression, please let me know!
