A stuntman is being shot out of a canon. Heīs following a track that is determinded by this equation:
y = 1 + 3x - 0,05x^2
where x meter is the horizontal distance from the canon and y meter is the height.
Will the stuntman be able to cross a gulch that is 58 metres wide?
Picture (I drew xD):
OPS! 56 m bred (swedish word for: width)
56 m bred = 56 m width
You mean ?
What were your solutions for y=0?
I donīt know how to solve this ...
That's a quadratic equation, as you say, so use the quadratic formula:
The solutions to are given by
Here, a= -0.05, b= 3, and c= 1.

Try it this way. Find . Then take the square root. Then calculate the rest. If you break it apart there's less chance of a calculation error. Just make sure you don't round off the intermediate steps. Keep, say, at least 5 digits.
