Dertermine whether ech binomial is the difference of two squares, If so, factor it, if not explain why?

Question

-m^6
36s^2-4t^2
9b^4-200
x^2-16
x^2y^2+196

Answer 1

-m^6. A binomial has 2 terms.

36s^2 - 4t^2.

(6s + 2t)(6s - 2t).

9b^4 - 200. The 2nd term(200) is not a perfect square.

X^2 - 16.
(X + 4)(X - 4).

X^2Y^2 + 196. This is the SUM of 2 squares.
