Answer 2

To solve the expression A² + 4ab - 3a²b - 6ab² + 4b², we need to look for common terms that can be combined. Let's rearrange the terms:

A² + 4ab - 3a²b - 6ab² + 4b²

Now, let's try to factor out common terms:

A² - 3a²b + 4ab - 6ab² + 4b²

The terms -3a²b and 4ab share a common factor of "a," and -6ab² and 4b² share a common factor of "b." Let's factor them:

a(A² - 3ab + 4b) - 2b(3ab - 2b)

Now, we have two binomial expressions:

1. A² - 3ab + 4b
2. 3ab - 2b

Each of these expressions has a common factor that we can factor out:

1. A² - 3ab + 4b can be factored as A² - (3ab - 4b) => A² - b(3a - 4)
2. 3ab - 2b can be factored as b(3a - 2)

Now, the final factored expression becomes:

A² - b(3a - 4) - 2b(3a - 2)

This is the simplified form of the expression. If you have specific values for A and b, you can further evaluate the expression numerically.
