Question

If the sum of two number is 40 and sum of their squares is 404,then the product of the number

Answer 1

Answer:

Step-by-step explanation:

Let numbers be x & y.

x+y=40

x=40-y

x^2+y^2=404

x^2=404-y^2

x=sqrt(404-y^2)

40-y=sqrt(404-y^2)

(40-y)^2=404-y^2

1600+y^2+80y=404-y^2

2y^2+80y+1196=0

factorise and simplify.....u will get the answer....
