Question

Find a pair of integer whose product is -50 and whose difference is 15

Answer 1

Answer:

5,-10

Step-by-step explanation:

let integers be x,y

x.y=-50....(1)

x-y=15....(2)

putting eqn 2 in 1

x.(x-15)=-50

→x²-15x+50=0

→x²-5x-10x+50=0

→x(x-5)+10(x-5)=0

→(x+10)(x-5)=0

→x= -10,5

if x= -10 ,y= 5
