ya im supposed to find the GCF but i don't think there is one so i dont know what to do
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
GCF ? first put x^2=y what u get ?
 one year ago

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
why would x^2 equal y
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
oh, it was just for simplification, u can put x^2 =t .... or z ..

hartnn Group TitleBest ResponseYou've already chosen the best response.1
i didn't mean that y on left side...
 one year ago

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
square root both sides
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
to find zeros of y=x^48x^2+16 u put y=0 x^48x^2+16=0 now if we put x^2 = t t^2 8t +16 = 0 this is quadratic in t, can u solve it ?
 one year ago

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
so just use the quadratic formula
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
or u can factor it .
 one year ago

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
the answer is 4 or 4 but the answer is supposed to be 2 or 2
 one year ago

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
how do i factor it
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
yes, because x^2 is 4,4

hartnn Group TitleBest ResponseYou've already chosen the best response.1
t^28t+16 = 0 t^2 4t 4t +16 = 0
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
what u got t as ?
 one year ago

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
im sorry what?

hartnn Group TitleBest ResponseYou've already chosen the best response.1
t^2 4t 4t +16 = 0 can u solve for t ?
 one year ago

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
no thats why i asked
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
t^2 4t 4t +16 = 0 factor out t from first 2 terms , what u get ?
 one year ago

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
i mean t(t8)+16=0
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
t^2 4t 4t +16 = 0 from this.... factor out t from 1st 2 terms....
 one year ago

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
thats what i thought i just did
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
u factored t from t^2 8t +16 = 0 i asked u to factor out t from t^2 4t 4t +16 = 0
 one year ago

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
t(t44)+16=0
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
i mentioned 'from first two terms' ...
 one year ago

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
t(t44t)+16=0
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
t^24t4t+16=0 t(t4) 4 (t4) = 0 did u get this ?
 one year ago

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
oh ok that makes sense
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
t(t4) 4 (t4) = 0 (t4)(t4) =0 i factored t4 from that, got this ?
 one year ago

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
how did u get rid of the t and 4 ouside the parentheses
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
i did not get rid of that...its in the 2nd brackets '()' ... (t4)
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
if u are getting confused let a=t4 t(t4) 4 (t4) = 0 ta4a = 0 a(t4)=0 now put back a= t4 (t4)(t4) = 0 got this ?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
so, t=4,4 which gives u x^2 = 4, 4
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
so whats x = ?
 one year ago

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
x=+or  the square root of 4
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.1
yes thats correct...x=2,2 for x^2 =4 now since x^2 = 4,4 ....u get x= 2,2,2,2 that is a root =2 with muliplicity 2 and another root =2 with multiplicity = 2
