Question

(а+2)^2 Подать а виде многочлена

Answer 1

(a+2)^2 = a^2 + 4a + 4

Answer 2

А²+2×2×а+2×2=а²+4а+4

Answer 3

To expand the expression (а+2)^2, we'll use the formula for squaring a binomial:

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

In this case, b = 2. So, the expression becomes:

(a + 2)^2 = a^2 + 2a(2) + 2^2

Now, simplify:

(a + 2)^2 = a^2 + 4a + 4

Thus, the expanded form of (а+2)^2 as a polynomial is:

a^2 + 4a + 4
