Question 1044393: Hello,
I need help with the following problem:
Undersea explorers discover a second sentient race living on Earth. This species is scientifically much more advanced but cannot share its discoveries because it uses a different system of units. Human scientists first try to convert between units of length: they measure a meter as 12 bap'ai and 2 bok'ai or alternatively 10 bap'ai and 10 bok'ai. In centimeters, how much distance is 5 bap'ai and 3 bok'ai?
Thanks,

Question 1035900: How to simplify this?
I did this equation here : y²-4y-x
Using bhaskara:
-(-4)±√(-4)²-4*1*(-1x)
----------------------- ->(this means a division)
2*1
And then, I got into this, and I don't know how to solve. Well, it's a forming Law of a function:
4±√16+4x
--------
