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

GCF ? first put x^2=y what u get ?

why would x^2 equal y

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 ..

square root both sides

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 ?
 2 years ago

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

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

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

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

t^28t+16 = 0 t^2 4t 4t +16 = 0

what u got t as ?

im sorry what?

t^2 4t 4t +16 = 0 can u solve for t ?
 2 years ago

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

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 ?
 2 years ago

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

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
thats what i thought i just did
 2 years 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

t(t44)+16=0
 2 years ago

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

t(t44t)+16=0
 2 years 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 ?
 2 years ago

mskyeg Group TitleBest ResponseYou've already chosen the best response.0
oh ok that makes sense
 2 years 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 ?
 2 years 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
 2 years 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)
 2 years 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 ?
 2 years ago

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

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

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