Question

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

Answer 1

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
