Question

Factor completely 25x^4y^6 − 1

Answer 1

(5x2y3+1)(5x2y3−1)

Explanation:

In this case, since this equation has both sides as a perfect square, you can apply the difference of squares formula a^2 - b^2 = (a+b) (a-b)

Applying this formula and factoring it accordingly leaves us off with (5x2y3+1)(5x2y3−1).
