-Use the given zero to find all the zeroes of the function:
function: f(x)=2x^3+3x^2+50x+75
zero: 5i



Thank you!!

Thank you!!

is a zero of f implies that its conjugate is also a zero of f then both and are factors of f and their product is a factor of
The quotient is divided by is

zeros of f are 5i, -5i, and -3/2
