The two numbers that multiply to make 25 and add to make 35 are 25 and 10. This is because 25 x 10 = 250 and 25 + 10 = 35. These two numbers satisfy both conditions simultaneously.
9 and -2
25 and 12
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.
