What two numbers add to -15 but multiply to 50

-10 and -5

Step-by-step explanation:

setting variables x and y to represent my two numbers

x+y = -15

xy = 50

y = -15-x (derived from first equation by isolating y)

plugging in y into the second equation

x(-15-x) = 50

factoring ...

(x+10)(x+5) = 0

x = -10, or -5

testing x = -10

-10+y=-15

y = -5

-10 * -5 = 50

your two numbers are -10 and -5

IF you wanted to test -5

-5 + y = -15

y = -10

-5 * -10 = 50

you get the same answer, but this will not always be the case

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

the answer is 99.
