    it was right! ok, and the last question is just like this - Find two numbers such that their sum is 12 and their product is 26.

    it might not be a whole number, if that helps. It might not be, but I'm not sure.

    6+sqrt(10) is one of the numbers, the other one you just do 12-(6+sqrt(10))

    6+sqrt(10) is bigger

    ok, that it now says that 6+sqrt(10) is correct, but the other one is still wrong

    the only clue I have is that the other answer is a smaller value

    you just do 12-(6+sqrt(10)). which is 6-sqrt(10)

    Set up an equation and solve the problem. Larry's time to travel 357 miles is 3 hours more than Terrell's time to travel 212 miles. Terrell drove 2 miles per hour faster than Larry. How fast did each one travel?
