hartnn Group TitleBest ResponseYou've already chosen the best response.1
is the original problem 21x^258x21 ?
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
right,so thats 21x^240x21=0 right ?
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
yeah and then the product of 21 and 21 is 441 and then 40 so the two numbers are 49 and 9
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
that is correct, see above u have written 49x  9x instead of what u got now as 49x+9x

eli123 Group TitleBest ResponseYou've already chosen the best response.1
oooh i see wow

hartnn Group TitleBest ResponseYou've already chosen the best response.1
now whats common from first 2 terms in 21x^249x9x21 =0?
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
i got the answer :P 3/7 and 7/3
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
yup, correct.

im having problems with another equation
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
i got to the point 9 + or  sqrt of 1 all over 4
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
9 from where ?
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
Compare your quadratic equation with \(ax^2+bx+c=0\) find a,b,c then the two rots of x are: \(\huge{x=\frac{b \pm \sqrt{b^24ac}}{2a}}\)

hartnn Group TitleBest ResponseYou've already chosen the best response.1
nopes, b is 4
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
oh wait nooo i gave you the wrong equation! no wonder
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
still b is 9
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
but in that equation it says b so (9) is 9
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
inside i did put put 9^2 = 81
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
yes, u are correct \(\huge\frac{9 \pm \sqrt{1}}{4}=\frac{10}{4},\frac{8}{4}\)
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
wait you are just adding and subtracting the 1?
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
obviously lol never mind i feel stupid
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
got it now ?
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
yes, it was a stupid moment :P
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
ok i did another one and i got 4+sqrt of 28 all over 2 @hartnn
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
its the first one that sent you
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
thats correct :)
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
but how do i factor it?
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
do u want to factor or do u want to use quadratic formula? anyways its not factorable....
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
so what would be the answer?
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
i cant simplify it?
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
all u can do is \(2 \pm \sqrt7\)
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
\(\sqrt{28}=2\sqrt7\)
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
how does that equal to that
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
\(\sqrt{28}=\sqrt{7*4}=\sqrt{7}\sqrt{4}=2\sqrt{7}\)
 2 years ago

eli123 Group TitleBest ResponseYou've already chosen the best response.1
you are the best!
 2 years ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
lol. glad to hear that :) u too are awesome ;)
