RE: Dividing by variable when solving algebraic equation
I'm teaching my 11th graders quadratic functions right now, they are not amused. Question: you have 100 meters of fence to fence in a rectangular area, but one of the sides doesn't need a fence because there's a wall already. So the question is, how long and wide do you choose your corral to maximize the area.

Hey! That's not fair. I've done my fair share of maths. You're not allowed to slip me that question  Tongue

Then again, I only got 50% in my own example.

If I don't win, the game is rigged.

In case it's not obvious, I love maths Big Grin Oh yeah. Always have. I asked for homework at my first school.

I like questions like that though, because they show a simple application of maths to a real situation where guesswork would only get you so far.

For those that are interested, this is how you get the answer:

E.g. x^2 + 4

Let's test where it intersects the x axis:

x^2 + 4 = 0

=> x^2 = -4

therefore, x = 2i

Also x = -2i

SEE WHAT I MEAN?!

are you OK, Rob o_o
