Question

Write a pair of integers whose product is -39 and whose difference is 16

Answer 1

Answer:

Step-by-step explanation:

let product =xy and difference =x-y

as xy=-39 and x-y=16

x=16+y-----(1)

substuting 1 in xy=-39

(16+y)y=-39

y^2+16y+39=0

splitting middle term

y^2+13y+3y+39=0

y(y+13)+3(y+13)

y=-13,-3

x=-3,-13
