6. Write a pair of integers whose product is -39 and whose difference is 16.
Answers
Answer:
Step-by-step explanation
4 and -4 are the pair of integers whose product is -16 and there lies seven integers between them excluding the given integers
Solution:
Given that,
Write the pair of integers whose product is -16
There lies seven integers between them excluding the given integers
From given,
product = -16
Let the two numbers be "a" and "b"
Consider a = 4 and b = -4
PRODUCT=4*-4=-16
Count the number of integers between them excluding the given integers
-3 , -2, -1, 0, 1, 2, 3
Thus, there are seven integers between them excluding the given integers
Answer:
The pair of integers are (13,-3) and (3,-13)
Step-by-step explanation:
xy= -39
x-y=16
x=16+y
(16+y)y= -39
y^2+16y+39=0
(y+3)(y+13)=0
y= -3 or -13
If y= -3 then x=13
If y= -13 then x=3
