Question

(d+l)2 = d2+dl+l2 1)Да 2)Нет

Answer 1

(d+l)²=d²+2dl+l²

Ответ: нет

Answer 2

1. Да

The given statement is correct. In algebra, the formula for squaring a binomial (a sum of two terms) is:

(a + b)^2 = a^2 + 2ab + b^2

In this case, we have (d + l)^2, where "d" and "l" are the two terms. Applying the formula:

(d + l)^2 = d^2 + 2dl + l^2

So, (d + l)^2 is equal to d^2 + dl + l^2.
