Question

Factor 9y 2 - 12y 4.

Answer 1

hope i understand it right

9y^2 -12y^4 = 3y^2 *(3 - 4y^2)

Answer 2

`3y^2(3 - 4y^2)` is the factored form

Explanation:

`9y^2 - 12y^4`

GCF of 9 and 12 is 3

GCF of variable is y^2

`9y^2 - 12y^4` Take out GCF 3y^2

`3y^2(3 - 4y^2)`

we cannot factor out 3-4y^2, because 3 is not a perfect square

`3y^2(3 - 4y^2)`
