Question

Factor 9y 2 - 12y 4.

Answer 1

hope i understand it right 

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

Answer 2

Answer:

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

Step-by-step 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

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