Find the number of possible positive real zeros of 2x^4+14x^3-35x^2

Possible zeros: Factors of P/Factors of Q, where P is the constant and Q is the leading coefficient.

P = 35: 1, 5, 7, 35

Q = 2: 1, 2

+1, - 1, + 1/2, - 1/2, + 5, - 5, + 5/2, - 5/2, + 7, - 7, + 7/2, - 7/2, + 35, - 35, + 35/2, - 35/2
