Re: quadraticsyou mean finding the roots of this quad eq ? Last edited by Chemist (20051213 11:55:37) "Fundamentally one will never be able to renounce abstraction." Werner Heisenberg #3 20051213 23:06:51
Re: quadraticsThe x intercepts are as Chemist already said, but the y intercept is 1, because the equation is 2x² + 4x +1. Why did the vector cross the road? It wanted to be normal. #5 20051214 01:53:18
Re: quadraticsYes, but what is the line intersecting with? We've already calculated where it crosses the axes. I agree that vertex wouldn't normally mean 'minimum point', but I couldn't think of what else it could mean. Why did the vector cross the road? It wanted to be normal.
