Question

Express (x + 6)2 as a trinomial

Answer 1

Answer:

$x^{2} +12x+36$

Step-by-step explanation:

$(x+6)^{2}$ 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 = $x^{2}$

Outer: x times 6 = 6x

Inner: 6 times x = 6x

Last: 6 times 6 = 36

so we have $x^{2} + 6x + 6x+36$

which becomes $x^{2} +12x+36$ when you combine like terms
