Hey this is 1:40! Kinda off from :60 :(
But good job anyway :)
-
fuck no! 4(3)(15) = 180!!!!!!!!!!!! WTF?
-
Yeh this works alright.
-
Haha Yeahh, well it was my friend who's really into maths, so he used my account to rant.... :L
-
floors??? LOL
-
which means that he ends up with -79 square rooted, and unless using imaginary numbers then negative square roots are not possible, another is that it's 100 seconds, but i salute your attempts and the working out would be fine, just a bad equation, and quadratics aren't and shouldn't always be solved with this method
-
no that is one of the floors, another is that on the fourth line he has 121-120, he states 4 x 3 x 15 is 120
-
He can't use the formula. How does he know that the original equation was equal to 0. It doesn't say so.
Ah ha, I've found the flaw
-
Yea I was just joking :)

Yes, anytime they leave out a "part" (an x^2, an x, or a number) that means there's zero of them, so you can place a zero there if you like.
