Question

form the polynomial whose zeroes are

Answer 1

sum of zeros=4+√2/2+4-√2/2
                     =4
product of zeros =(4+√2/2)(4-√2/2)
                            =16-2/4
                              =7/2
quadratic equation is x^2-(sum of zeros)x+(product of zeros)
                                  x^2-4x+7/2=0
                                  2x^2-8x+7=0
