Question

(m+n)^2____________​

Answer 1

Формула квадрата суммы

(m + n)² = m² + 2mn + n²

Answer 2

Здравствуй!

Как я понимаю, надо разложить...

(m+n)² = m² + 2mn + n²

Answer 3

The expression (m + n)^2 represents the square of the sum of two variables, m and n. To simplify this expression, you can expand it using the distributive property. Here's how it's done:

(m + n)^2 = (m + n) * (m + n)

Now, you can use the distributive property to multiply these two binomials:

(m + n) * (m + n) = m * (m + n) + n * (m + n)

Now, distribute m and n into the parentheses:

m * (m + n) = m^2 + mn n * (m + n) = mn + n^2

So, putting it all together:

(m + n)^2 = m^2 + mn + mn + n^2

Now, combine like terms:

(m + n)^2 = m^2 + 2mn + n^2

So, (m + n)^2 simplifies to m^2 + 2mn + n^2.
