Question

The sum of two integers is -11 and their products os -80 . What are the two integers?

​

Answer 1

Answer:

Rule: The sum of any integer and its opposite is equal to zero. Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.

Answer 2

Step-by-step explanation:

Let one of the integers be X.

Another integer = -11 - x

Product of the integers = - 80

ATQ,

X ( -11 - X) = -80

or, - X ( 11+x) = - 80

or, X ( 11 + X) = 80

or, 11x + X square = 80

or, X square + 11 X - 80 = 0

or, X square + 16x - 5x -80 = 0

or, X ( X + 16) - 5( X +16) = 0

or, (x+16) ( X -5 ) =0

or, X = -16 , 5

The required integers are -16 ,5.
