Find a polynomial of degree n that has only the given zeros
Find a polynomial of degree n that has only the given zero(s). (There are many correct answers.)
x = 0, sqrt(3) , -sqrt(3) ; n = 3
Solution
given zeros are
a = 0
b = sqrt 3
c = - sqrt 3
polynomial would be
p(x) = (x-a) (x-b)(x-c)
plugging the values of a,b,c
p(x) = (x-0) (x-sqrt 3) (x-(-sqrt3 ))
p(x) = (x) (x- sqrt 3 ) (x+ sqrt 3)
p(x) = x (x^2 - 3) = x^3 - 3x
hence , polynomial is p(x) = x^3 - 3x
