Question

(9q+2)^2...............

Answer 1

81q^2 + 36q + 4 - это ответ

Answer 2

To expand the expression (9q + 2)^2, you can use the FOIL method (First, Outer, Inner, Last) or the general formula for squaring a binomial:

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

In this case, a = 9q and b = 2. Now, let's expand it:

(9q + 2)^2 = (9q)^2 + 2 * 9q * 2 + 2^2 = 81q^2 + 36q + 4

So, the expanded form of (9q + 2)^2 is 81q^2 + 36q + 4.
