Answer 2

Ответ:

а+4а²+4а³

Объяснение:

a(1+2a)²=а(1+4а+4а²)=а+4а²+4а³

Answer 3

To square the expression A(1+2a), you can use the distributive property and then apply the square to each term within the parentheses:

A(1+2a)² = A(1+2a)(1+2a)

Now, let's use the distributive property to expand this expression:

A(1+2a)(1+2a) = A(11 + 12a + 2a1 + 2a2a)

Simplify this further:

A(1 + 2a + 2a + 4a²)

Now, combine like terms within the parentheses:

A(1 + 4a + 4a²)

Finally, you can distribute A into each term:

A + 4aA + 4a²A

So, A(1+2a)² = A + 4aA + 4a²A
