I got x^2-25. is this correct?

OpenStudy (anonymous):

well can you factor that multiple times?

OpenStudy (anonymous):

me thinks not

OpenStudy (anonymous):

I dont' know what it means to be able to factor it multiple times

OpenStudy (anonymous):

do you know how to factor?

OpenStudy (anonymous):

Sort of. I can FOIL to check my factors easily, but I don't know if i can factor

OpenStudy (anonymous):

well you can factor x^2-25 to be (x+5)(x-5), but then you can't factor anymore the trick to factoring is looking at that -25, and thinking of two numbers that when multiplied by each other = -5, but when added = 0

OpenStudy (anonymous):

I on't think there are any numbers that do that. why -5?

OpenStudy (anonymous):

sorry i meant -25*** just a typo

OpenStudy (anonymous):

(also there are two numbers that when multiplied by each other = -5, but when added = 0........ but that's not really important)

OpenStudy (anonymous):

5 and -5!

OpenStudy (jhannybean):

mmhmm.
