Question

The difference between two numbers is 9 and the product
of the numbers is 162. Find the two numbers.

Answer 1

x-y = 9

x*y = 162

x = y +9

(y+9)*y = 162

y²+9y = 162

y²+9y-162=0

y= 9 or

y= -18

x-9= 9

x = 9+9

x = 18

x-(-18) = 9

x+18 = 9

x= 9-18

x = -9

So, if x = 18, y will be 9

If x = -9, y will be -18
