Answer

Perfect-square trinomial Explanation 1. Identify the form of the polynomial The polynomial \( x^{2}+12x+36 \) is a trinomial with three terms. 2. Check for perfect-square trinomial A perfect-square trinomial has the form \( (a+b)^2 = a^2 + 2ab + b^2 \). Here, \( a^2 = x^2 \), ( 2ab = 12x ), and \( b^2 = 36 \). 3. Verify perfect-square conditions Solving gives ( a = x ) and ( b = 6 ), since ( 2ab = 12x ) implies ( 2(x)(6) = 12x ).
