Question

if one zero of the polynomial x2 -4 +1 is 2 + √3 write the other zeroes​

Answer 1

Answer:

x²-4x+1

zeroes ⇒2+√3  

let the unknown zero be'α'

in thi equation product of zeroes = c/a = 1/1 = 1

                             (2+√3) × (α)    = 1

                                             α      = 1÷ 2+√3

                                                       = 1 / (2+√3)
