The property that defines a perfect square trinomial is that the second term is 2 times the product between the squares of each square term.
Step-by-step explanation:
Option A is true, <u>but is not a property,</u> is a condition of the definition of a perfect square trinomial
Option B is true, <u>but is neither a property</u>, is also a condition of the definition of a perfect square trinomial.
Option C is true, and is a property of the trinomial, because this property, is the one which allows to apply the defined simplification for a perfect square trinomial: [tex]a^2±2ab+b^2=(a±b)^2[tex/]
The slope increases at a rate of 1 / 1, which is written as just x. The line starts at 2, which is at the y-intercept, a.k.a, where you get the +2 from.
