Question

Выполните умножения (а+1)(а+1)

Answer 1

(а+1)(а+1)=a^2+a+a+1=a^2+2a+1
Вообще это формула сокращенного умножения
(а+1)(а+1)=(a+1)^2=a^2+2a+1

Answer 2

(а+1)(а+1)=а^2+2a+1       (а^2-а в квадрате)     

Answer 3

Multiplying (a+1)(a+1)

To multiply (a+1)(a+1), we can use the distributive property, which states that for any real numbers a, b, and c: a(b + c) = ab + ac.

So, for (a+1)(a+1): - First, we multiply the first terms: a * a = a^2. - Then, we multiply the outer terms: a * 1 = a. - After that, we multiply the inner terms: 1 * a = a. - Finally, we multiply the last terms: 1 * 1 = 1.

Putting it all together, we get: a^2 + a + a + 1

Simplifying, we get: a^2 + 2a + 1

Therefore, the result of multiplying (a+1)(a+1) is a^2 + 2a + 1.
