Question

find the no whose product is -6 and sum is 12​

Answer 1

Answer:

let the no s be x and y

xy=-6

x+y=12

y= -6/x

x - 6/x = 12

x^2 -12x - 6 = 0

roots (x) =

(12 + √144 + 24. )/2

x = 6 + (√168 /2) and 6 - (√168 / 2)

these are two acceptable values of X and now you can get y by putting x in

y= -6/x
