Question

The difference of two numbers is 20 and there product is 125. what are the two numberrs?

Answer 1

let 2 numbers are x and y.

then according to question,

x - y = 20

so, x = y + 20

x * y = 125

(y +20) * y = 125

y^2 + 20y =125

y^2 + 20y - 125 = 0

y^2 + 25y - 5y - 125 = 0

y(y + 25) - 5(y + 25) = 0

(y -5) (y + 25) = 0

so, y = 5 , -25

then,

x = y + 20

y= 25 , -5
