Tips

Post  Admin on Sat Oct 16, 2010 7:20 pm

a. We have still yet to show HOW AB^2 = the quadratic - tip: plot points and use pythagoras!

b. Federico is pretty close- we can get values of k which are whole numbers by factorsing the equation.

Fergus well done! that looks correct to me..
The 10 is a given- see question

I guess Ali's answer's are also correct. k=-5 or 7. Well done all!
