Question

The suml of two integer is -11, and their product is -80, what are the two integers?

Answer 1

Solution:

Let x and y be the two integer.

Sum of the two integer:

x+y=-11, so
if x = -16 and y = 5, we substitute this values to their corresponding variable,
we got
-16+5=-11

Product of the two integer:

x*y=-80, so
if x = -16 and y = 5, we substitute this values to their corresponding variable,
we got
-16*5=-80.

Therefore, the two integer are -16 and 5.
