How do you find all zeros of #f(x)=1/3x^2+1/3x-2/3#? Precalculus Polynomial Functions of Higher Degree Zeros 1 Answer Shwetank Mauria Jun 1, 2017 Zeros of #f(x)# are #x=1# and #x=-2#. Explanation: #f(x)=1/3x^2+1/3x-2/3=1/3(x^2+x-2)# = #1/3(x^2+2x-x-2)# = #1/3(x(x+2)-1(x+2))# = #1/3(x-1)(x+2)# Hence, zeros of #f(x)# are #x=1# and #x=-2#.
