fuck!i got 33 seconds i think and 4000+metres
that was 7a) im talking about 7b) the tan one.

yeah i think you confirmed it. stupid calculator.
Hermes1 already posted substitution. You have still not shown your substitution leading to nonzero. Either you made an error maybe because you used a wrong polynomial or you have problems with your algebra - in which case you need to address.just substitute back to the original equation : i tried wolfram and i got this -7.105427357601×10^-15 but alternative form is 0. maybe it is a root.
lol'd. I wrote "because it only crosses the x-axis once" I had no idea. LolIn the graphing question - why does the graph only have 1 x-intercept?
LOOOOOOOOOOOOL. thats classic. hope u get the mark.lol'd. I wrote "because it only crosses the x-axis once" I had no idea. Lol
sweet did that aswell except showed it with derivatives.. is that the correct approach?the graph is increasing, so at x = -1.2, y = 0
that means that for x > -1.2, y > 0 and if x < -1.2, y < 0
therefore it will never hit x axis again so 1 x -int
i didnt think about substitution because it will be too much working. so i tried perfect square and all those methods that i know, and putted into my stupid calculator, they all gave me this stupid small number, and these stupid small numbers make me stupidly stress.Hermes1 already posted substitution.

Edit
don't blame stupid calculator!
I won't. My teacher is very mean about giving marks. She doesn't like to give them away.LOOOOOOOOOOOOL. thats classic. hope u get the mark.
did u hav enuff time to go over the exam. did u manage to finish early?FUUUUARK
The more i tihnk about the exam, the more i think i got wrong
(2+root3)^3 - 15 (2+root3) + 4can you list the sequence of inputs into yr calculator? step by step without ommision. we'll see where you boo bood.
the only way u could have got it wrong wuld be if u entered one of the signs wrong. did u at least leave the answers on the page?(2+root3)^3 - 15 (2+root3) + 4
btw, it's a sharp calculator.
i finished with 30min to spare but still not feeling confident D:did u hav enuff time to go over the exam. did u manage to finish early?
lol this is equal to zero..(2+root3)^3 - 15 (2+root3) + 4
