Question 604906: the sum of 2 numbers is 12, and their product is 35. Find the numbers.
Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! "the sum of 2 numbers is 12" ---> x+y = 12 ---> y = 12-x
----------------------------
"their product is 35" ----> xy = 35
xy = 35
x(12-x) = 35
-x^2 + 12x = 35
-x^2 + 12x - 35 = 0
x^2 - 12x + 35 = 0
(x - 7)(x - 5) = 0
x-7 = 0 or x-5 = 0
x = 7 or x = 5
So the two numbers are 5 and 7
