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 ?

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

i didn't mean that y on left side...

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 ?

mskyegBest ResponseYou've already chosen the best response.0
so just use the quadratic formula

the answer is 4 or 4 but the answer is supposed to be 2 or 2

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

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

t^2 4t 4t +16 = 0 factor out t from first 2 terms , what u get ?

hartnnBest ResponseYou've already chosen the best response.1
t^2 4t 4t +16 = 0 from this.... factor out t from 1st 2 terms....

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

hartnnBest 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

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

t^24t4t+16=0 t(t4) 4 (t4) = 0 did u get this ?
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
t(t4) 4 (t4) = 0 (t4)(t4) =0 i factored t4 from that, got this ?

how did u get rid of the t and 4 ouside the parentheses
 one year ago

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

hartnnBest 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 ?

hartnnBest ResponseYou've already chosen the best response.1
so, t=4,4 which gives u x^2 = 4, 4

x=+or  the square root of 4
 one year ago

hartnnBest 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
