Пошаговое объяснение:

=4а^2 - 4аб+2аб-4б^2 =4а^2 - 2аб-4б^2

Answer 2

To simplify the expression 4a(a-b) + 2b(a-2b), we can use the distributive property and then combine like terms. Here's the step-by-step simplification:

Step 1: Distribute the terms inside the parentheses: 4a(a - b) = 4a^2 - 4ab 2b(a - 2b) = 2ab - 4b^2

Step 2: Combine the like terms (terms with the same variables and exponents): 4a^2 - 4ab + 2ab - 4b^2

Step 3: Combine the middle terms (-4ab + 2ab): 4a^2 - 2ab - 4b^2

So, the simplified expression is: 4a^2 - 2ab - 4b^2.
