Can anyone please suggest steps on how to solve that kind of problem? Specifically, I'm solving for the minimum distance between the parabola y^2 = 8x and the point (6,0). Thanks! :-)

I know the common method is to multiply it three times. But, that would require paper and pen / pencil. I want to learn the mental calculation method. Please let me know how.
Thanks

They want it simplified, and their answer is -1 over 1+t and I have no idea how they got it... I don't know if it is 1-(t squared) or (1-t)squared. I ended up with -1 over 1-t, not 1+t . What am I doing wrong?

All planets have a gravitational pull, but would other objects too? If there was a pen floating around in space would smaller objects be attracted to it? If this is true, How light would something have to be to be pulled in by a 10 pound weight in space?
