SOLUTION: We are supposed to factor polynomial. They say: (x^2+y^2)^2-(y^2-z^2)^2 should equal (x^2+z^2)(x^2+2y^2-z^2).

Question 68797: We are supposed to factor polynomial. They say:
(x^2+y^2)^2-(y^2-z^2)^2 should equal (x^2+z^2)(x^2+2y^2-z^2).

factor polynomial. They say:
(x^2+y^2)^2-(y^2-z^2)^2
This follows the form a^2-b^2=(a-b)(a+b)
You get:
[(x^2+y^2)+(y^2-z^2)]
