Question

question
factor completely.
$1 - x^2y^4$
answer attempt 1 out of 3

Explanation:

Step1: Recognize difference of squares

$1 - x^2y^4 = 1^2 - (xy^2)^2$

Step2: Apply difference of squares formula

$a^2 - b^2=(a-b)(a+b)$, so $1^2 - (xy^2)^2=(1-xy^2)(1+xy^2)$

Answer:

$(1 - xy^2)(1 + xy^2)$
