Question

Products is -1 sum is -1 what are numbers

Answer 1

let two numbers be x and y

xy=-1

x+y=-1

x=-1/y put in x+y=-1

-1/y+y=-1

(y)^2+y-1=0

y=-b+√{(b)^2-4ac}/2a

y=(-1+√1+4)/2

y=(-1+√5)/2

or y=(-1-√5)/2 put in x+y=-1

x+(-1+√5)/2=-1

x=-1-(-1+√5)/2=(-2+1-√5)/2

x=(-1-√5)/2

two numbers are (-1-√5)/2 & (-1+√5)/2
