Question

find number with sum 6 and product 9?​

Answer 1

Answer:

let x and y are the no. whose sum = 6

and product = 9

x + y = 6

=> x = 6-y

xy = 9

(6-y)y = 9

-y²+6y = 9

y²-6y+9 = 0

y²-3y-3y+9=0

y(y-3)-3(y-3)=0

(y-3)(y-3)=0

so, y= 3,3

put this value in below equation

x=6-y

x=6-3

x = 3
