Question

Item 2

Answer 1

Option B and Option C are correct options

Step-by-step explanation:

A perfect square trinomial is one that can be written in form:

$a^2+2ab+b^2=(a+b)^2$

Now checking options:

Option A:

$y^2+25y+200$

This option is incorrect because $y^2+25y+200$ cannot be written in (a+b)^2 because 200 is not a perfect square of any number

Option B:

$y^2+18y+81$

This option is correct because it can be written in (a+b)^2

Solving

$=(y)^2+2(y)(9)+(9)^2\\=(y+9)^2$

Option C:

$y^2+20y+100$

This option is correct because it can be written in (a+b)^2

Solving

$=(y)^2+2(y)(10)+(10)^2\\=(y+10)^2$

Option D:

$y^2+6y+36$

This option is incorrect because it can be written in (a+b)^2

So, Option B and Option C are correct options
