eli123Best ResponseYou've already chosen the best response.1
idk how i got 7x(3x7) 3(3x7) and i know its wrong
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
is the original problem 21x^258x21 ?
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
right,so thats 21x^240x21=0 right ?
 one year ago

eli123Best 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
 one year ago

hartnnBest 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
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
now whats common from first 2 terms in 21x^249x9x21 =0?
 one year ago

eli123Best ResponseYou've already chosen the best response.1
i got the answer :P 3/7 and 7/3

eli123Best ResponseYou've already chosen the best response.1
im having problems with another equation
 one year ago

eli123Best ResponseYou've already chosen the best response.1
i got to the point 9 + or  sqrt of 1 all over 4
 one year ago

hartnnBest 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: \(\huge{x=\frac{b \pm \sqrt{b^24ac}}{2a}}\)
 one year ago

eli123Best ResponseYou've already chosen the best response.1
oh wait nooo i gave you the wrong equation! no wonder
 one year ago

eli123Best ResponseYou've already chosen the best response.1
but in that equation it says b so (9) is 9
 one year ago

eli123Best ResponseYou've already chosen the best response.1
inside i did put put 9^2 = 81
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
yes, u are correct \(\huge\frac{9 \pm \sqrt{1}}{4}=\frac{10}{4},\frac{8}{4}\)
 one year ago

eli123Best ResponseYou've already chosen the best response.1
wait you are just adding and subtracting the 1?
 one year ago

eli123Best ResponseYou've already chosen the best response.1
obviously lol never mind i feel stupid
 one year ago

eli123Best ResponseYou've already chosen the best response.1
yes, it was a stupid moment :P
 one year ago

eli123Best ResponseYou've already chosen the best response.1
ok i did another one and i got 4+sqrt of 28 all over 2 @hartnn
 one year ago

eli123Best ResponseYou've already chosen the best response.1
its the first one that sent you
 one year ago

eli123Best ResponseYou've already chosen the best response.1
but how do i factor it?
 one year ago

hartnnBest 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....
 one year ago

eli123Best ResponseYou've already chosen the best response.1
so what would be the answer?
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
all u can do is \(2 \pm \sqrt7\)
 one year ago

eli123Best ResponseYou've already chosen the best response.1
how does that equal to that
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
\(\sqrt{28}=\sqrt{7*4}=\sqrt{7}\sqrt{4}=2\sqrt{7}\)
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
lol. glad to hear that :) u too are awesome ;)
 one year ago

eli123Best ResponseYou've already chosen the best response.1
lol thank you, well i gotta keep doing this stupid hw
