Answer 2

Step-by-step explanation:

Square the binomial (x + 6).

Solution. (x + 6)2 = x2 + 12x + 36

x2 is the square of x.

12x is twice the product of x with 6. (x · 6 = 6x. Twice that is 12x.)

36 is the square of 6.

x2 + 12x + 36 is called a perfect square trinomial -- which is the square of a binomial.
