How do you find all the zeros of # f(x) = (x + 3)(x – 1)(x – 5)#? Precalculus Polynomial Functions of Higher Degree Zeros 1 Answer Shwetank Mauria Mar 16, 2016 #{-3,1,5}# are zeros of #f(x)=(x+3)x-1)(x-5) Explanation: Zeros of #f(x)# are those values of #x#, which make #f(x)=0#. As #f(x)=(x+3)x-1)(x-5)#, #f(x)# will be zero, if #x+3)=0# or #x-1)=0# or #(x-5)=0# i.e. #x=-3# or #x=1# or #x=5# Hence, #{-3,1,5}# are zeros of #f(x)=(x+3)x-1)(x-5)# Answer link Related questions What is a zero of a function?
