Question

The sum and product of two numbers are 12 and 35, respectively. what is their difference?

Answer 1

x+x=12
x×x=35
2x=12
x=6
x=35/2
35/2-6

Answer 2

Hi !

Let the two no:s be "x" and "y"

given :-

x + y = 12
x = 12 - y

xy = 35
(12 - y)y = 35
12y - y² = 35

-y² + 12y - 35 = 0
y² - 12y + 35 = 0
( y - 7) ( y - 5 ) = 0

The no:s are 7 and 5 .
Their difference = 7 - 5 = 2
