Question

What are the possible number of positive real, negative real, and complex zeros of f(x) = –7x4 – 12x3 + 9x2 – 17x + 3?

Answer 1

the possible number of 0s is always the same as the degree of the polynomial, so in this case, 4.

Answer 2

however its important to note that that is the greatest amount of 0s the polynomial could have, in this case it only has 2.
