(2r3 + a)(r3 + 1)
6 + 2r3 + ar3 + a / 2
6 + a + r3(2 + a) / 2
#chat why is this wrong it looks right to me
brazen warren
You multiplied top and bottom by √3-1
You need to multiply by the conjugate
Which is √3+1
sinful kestrel
What's your working
we dont have a box for that. just answer box
sinful kestrel
(2r3 + a)(r3 + 1)
6 + 2r3 + ar3 + a / 2
6 + a + r3(2 + a) / 2
so its the same but... written a different way essentially?

Mate I was asking what you did
opaque chasm

No
opaque chasm
i thought i did the same as you but clearly not
Whatdid you multiply by
sinful kestrel
Whatdid you multiply by
root 3 + 1
opaque chasm
I did that
opaque chasm
,w rationalise (2sqrt(3) + a ) / (sqrt(3) - 1)
sinful kestrel
pls
opaque chasm
,w rationali\e (2sqrt(3) + a ) / (sqrt(3) - 1)
,w rationalize (2sqrt(3) + a ) / (sqrt(3) - 1)
vale hare
,w derivate y = (x-6)(x+4)

ye i dont see how thats wrong either
vale hare
is there a way to label the points or something
cobalt veldt
did u show the y axis intersection
vale hare
thats it
sinful kestrel
did u show the y axis intersection
but im only given 3 points
sinful kestrel
try expanding the brackets
whats that got to do with it
i found the turning point already
vale hare
just do it blud
sinful kestrel
just do it blud
seems like a waste of time, but i can tell you the y intercept would be -24
just by looking at it
sinful kestrel
well, im stumped. most of the other questions are piss easy
mortal olive
@sinful kestrel do u still need help
signal nacelle
what about this. this is wrong apparently
y intercept is not -25
,w turning point of x²-2x-24
