Final Answer:

The two numbers that give you -36 when multiplying but when adding them give you 16 are 6 and -6.

Step-by-step explanation:

Let x and y be the two numbers we are looking for. We know that xy = -36 and x + y = 16.

From the second equation, we can express y in terms of x:

y = 16 - x

Substituting this expression for y into the first equation, we get:

x(16 - x) = -36

Expanding this expression, we get:

16x - x² = -36

Moving all terms to one side, we get:

x² - 16x + 36 = 0

Factoring this expression, we get:

(x - 6)(x - 6) = 0

Therefore, x = 6. Substituting this value of x back into the equation y = 16 - x, we get:

y = 16 - 6 = 10

Therefore, the two numbers that give you -36 when multiplying but when adding them give you 16 are 6 and 10.
