Which polynomial represents a perfect square polynomial. Select all that apply
Hunter-Best [27]

ANSWER

{x}^{2}  - 2x + 1

and

{x}^{2}   +  2x + 1

EXPLANATION

A perfect square trinomial can be written in the form:

(a - b) ^{2}  =  {a}^{2}  - 2(ab) +  {b}^{2}

or

(a  +  b) ^{2}  =  {a}^{2}   + 2(ab) +  {b}^{2}

For the first option;

(x  + 1) ^{2}  =  {x}^{2}   + 2(x)(1)) +  {1}^{2}

This is a perfect square trinomial.

For the second option,

(x   - 1)^{2}  =  {x}^{2}    - 2(x)(1)) +  {1}^{2}

This is also a perfect square trinomial.

The third option

4 {x}^{2}   + 12x + 16

This cannot be written as a perfect square.

4 {x}^{2}  - 12x - 9

This cannot also be written as a perfect square.
