TheNinja gets 5 points. t^2 - 4t + 7 = 0 You'll quickly notice that this parabola has no real solutions: the solutions are therefore two different imaginary solutions. t = 2 + i*1.73205 V t = 2 - i*1.73205 (V = or) Oops, it's x=-10 and x=5!!!! martin that's the right answer :D  OK! I figured it out! He bought 7 eggs. @AK: 4x-7=48 x= 55/4 MARC2008:Can I get the points?;) (x-2)(x+1)/ x=2, x=-1 Puzzle:1 egg [edit] difficulty: medium [3P] factorise: x^2-5x+50 [edit] I mean x^2+5x-50 [re-edit] also here's a puzzle(hard, 7P): there's a house and a market with 3 toll bridges between them a man goes to the market, he doesn't have to pay to cross the bridges on the way there. he buys x eggs, but has no money left so to pay the toll bridge fee he pays half the eggs in his basket plus half an egg. he has no eggs after rossing them all. what is x? =10.25 or 10 1/4 or 41/4 New question(4p); 4x-7=48 x= Keep in a fraction! At least then I know its 5.3662479...  I think I'm more accurate. 
How many points do I get? I also realised I work at 2-3 times the speed of my class XD [edit] may I ask a question? Next:(6p) t^2-4t+7=0 Use the quadratic formula and solve for both values of t! | GeneralFirst post of the topic Here we go! First question(1p) 6-2=?
