Which of the following are properties of a perfect square trinomial?a) the first and third terms must be perfect squares b) neither of the perfect squares can have a minus sign c)if the square terms are a2 and b2 then the other term must be 2ab. d) none of the above is a properties of a perfect square trinomial

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, but is not a property, is a condition of the definition of a perfect square trinomial Option B is true, but is neither a property, 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/]
