The numbers: x, y
x·y=-14
x+y=5 ⇒ y=5-x
Substitute y in the first equation by y from second one
x·(5-x)=-14
5x-x²=-14
-x²+5x+14=0
-x²-2x+7x+14=0
-x(x+2)+7(x+2)=0
(x+2)(-x+7)=0
Product is 0 if one of factors is 0
x+2=0 or -x+7=0
x=-2 or -x=-7
x=-2 or x=7
Now back to the equation y=5-x
y=5-(-2) or y=5-7
y=7 or y=-2
The numbers are -2 and 7
The answer is C. If you subtract the lesser amount from the greater amount then you get the difference between the two and how far they were to each other. Maybe Jamal needs to get more exercise to beat Kylie.
