Question

Factor completely 25m^2-9

Answers

GPT 3.5
We will factor completely the given expression:

25m^2 - 9

This expression is a difference of squares, as it can be rewritten as:

(5m)^2 - 3^2

The difference of squares formula states that a^2 - b^2 = (a + b)(a - b)

Therefore, applying this formula to our expression, we get:

(5m + 3)(5m - 3)

So, the given expression is factored completely as 25m^2 - 9 = (5m + 3)(5m - 3).

Yes, that's correct. I apologize for the oversight in my explanation. The correct factorization of 25m^2 - 9 using the difference of squares formula is:

25m^2 - 9 = (5m - 3)(5m + 3)

Thank you for pointing that out.
