Science & Mathematics - 18 June 2006

I know the formula: x= -b +/- square root (b^2- 4ac), divided by 2a.

So, let's say the equation is 15x^2+7x-55

How would you do it?
What is your answer if the problem tells you to "Solve using the quadratic formula?"

Thanks!

the surface temperature of venus is
1)warmer due to absorption of long-wave(infrared)by green house gas
2)warmer due to the absorbation of short waves (ultravilote)
radiation by green house gas

There are sites that constantly watch the skies, and there are things out in Space that we are still learning about.
I wonder if anyone has had a personal experience or knows of someone who has....
What was Si-Fi in 1900 and later...is now real...so when I look at a modern Sci Fi movie, I wonder if my grand children will be travelling further than I can..

When seeds are planted, what is the biological or chemical reaction that happens that makes a plant? Almost any soil, conditions, as long as there is enough moisture or water to support life. The tiny seed has some kind of code that is programmed that makes that particular plant have it's characteristics. We don't think about it, but it is a miraculous event.
