#### Answer

$(x^2-y^5)(x^2+y^5)$

#### Work Step by Step

RECALL:
A difference of two squares can be factored using the formula:
$a^2-b^2=(a-b)(a+b)$
The given binomial can be written as:
$=(x^2)^2-(y^5)^2$
This binomial is a difference of two squares.
Factor the given difference of two squares using the formula above with $a=x^2$ and $b=y^5$ to obtain:
$=(x^2-y^5)(x^2+y^5)$
