HELP PLEASEEE I NEED HELP QUICK

Which of the following are properties of a perfect square trinomial? Select all
that apply.
A. The first and third terms must be perfect squares.
B. Neither of the perfect
squares can have a minus sign.
C. If the perfect square terms are A2 and B2 then the other term
must be 2 AB or -2AB.
D. None of the above is a property of a perfect square trinomial.

Answer 1

C) If the perfect square terms are A^2 and B^2 and other terms must be 2 AB and -2AB

Explanation:

As,

`(a^2+2ab+b^2)=(a+b)^2\\(a^2-2ab+b^2)=(a-b)^2`

Answer 2

A, B and C

Explanation:

The Perfect Squares are the squares of the integers

Perfect square trinominal is: a² ± 2ab + b² {which is (a±b)²}

So:

The first and third terms must be perfect squares and neither of the perfect squares can have a minus sign and If the perfect square terms are A2 and B2 then the other term must be 2AB or -2AB
