Question

Are there factors of 144 that add/subtract to -25?

Answer 1

Are you trying to factor using the FOIL method?

Answer 2

Yes

Answer 3

Then yes it would be -9 and -16. Assuming your problem looks something like this: x^2-25x+144. Factored that would be: (x-9) (x-16)

Answer 4

That seems right
