Option 1,2 and 5 represent a perfect square monomial and its square root.

Step-by-step explanation:

To find : Which expressions represent a perfect square monomial and its square root? Check all that apply.

Solution :

1) 121, 11

As

This expression represents a perfect square monomial and it’s square root.

2)

As

This expression represents a perfect square monomial and it’s square root.

3)

As

This expression does not represents a perfect square monomial and it’s square root.

4)

As

This expression does not represents a perfect square monomial and it’s square root.

5)

As

This expression represents a perfect square monomial and it’s square root.

Therefore, Option 1,2 and 5 represent a perfect square monomial and its square root.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
