Answer 1

Answer:

A perfect square is a number that is resulted by the other number raised by 2.

For example: 36 is a perfect square, because 6² = 36.

A perfect square trinomial is a trinomial that is resulted by a squared-binomial.

in other words, (x² + 2x + 1) is a perfect square trinomial, because it can be expressed by the square- binomial form as (x+1)²
