Answer:
[tex]x^{2} +12x+36[/tex]
Step-by-step explanation:
[tex](x+6)^{2}[/tex] can also be written as (x+6)(x+6), because "squared" just means "times itself"
Knowing this you can use FOIL to turn it into a Trinomial
First: x times x = [tex]x^{2}[/tex]
Outer: x times 6 = 6x
Inner: 6 times x = 6x
Last: 6 times 6 = 36
so we have [tex]x^{2} + 6x + 6x+36[/tex]
which becomes [tex]x^{2} +12x+36[/tex] when you combine like terms
