    possible zeros come from factors of 6 therefore: 1, -1, 2, -2, 3, -3 But mostly, you try 1 and -1 first

    That is a fact. Possible zeroes come from factors of the coefficient independent of x

    Use the remainder theory to find the zeroes for the polynomial

    if P(x) = 0, x is a zero.

    2x^5+3x^3+5x^2-6 = 0 No of possible for Real Positive roots is 1 no of possible for Real -ve roots is 2 or 0

    since f(0)<0 and f(1)>0 one root is between 0 and 1

    root is 0.83271 it is not integer, so it is not easy
