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

Best ResponseYou've already chosen the best response.1to 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 ?

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

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

Best ResponseYou've already chosen the best response.1u factored t from t^2 8t +16 = 0 i asked u to factor out t from t^2 4t 4t +16 = 0

Best ResponseYou've already chosen the best response.1t^24t4t+16=0 t(t4) 4 (t4) = 0 did u get this ?

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

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

Best ResponseYou've already chosen the best response.1if 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 ?

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

Best ResponseYou've already chosen the best response.0x=+or  the square root of 4

Best ResponseYou've already chosen the best response.1yes 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
