The only factors of 25 are: 1, 5, and 25. None of those factors add up to 9, let alone add up to 9 and multiply to 25. If you were trying to solve for x in a quadratic equation, you may need to use the quadratic formula.

Assuming a = 1, b = 9, and c = 25 (x^2 + 9x + 25):

x = (-b +- sqrt(b^2 - 4ac)) / 2a

x = (-9 +- sqrt(9^2 - 4(1)(25)) / 2(1)

x = (-9 +- sqrt(81 - 100)) / 2

x = (-9 +- sqrt(-19)) / 2

Final Answer:

x = (-9 +- i*sqrt(19)) / 2

If you've written that correctly, there aren't two whole numbers that satisfy those conditions. -20 and -5 add to -25, but multiply to 100. -25 and 4 multiply to -100, but add to -21.
