state all possible rational zeros for the function
here is one of the problems i'm having trouble with:
f(x)= x^3+2x-3x+5
i know: p= +1, -1, +5, -5
q= same
but none of them seem to equal to zero when i put them in <---me
one that i have NO IDEA how to do is:
find all rational zeros for each function
f(x)= (x-3)(x+5)(2x+5)
Thanks for any help in advance -Liza
