Question 57102: I need help listing the possible rational zeros of f(x)= 4x^3+12x^2-x+15, by using the rational zeros theorem. Could anyone help?

You can put this solution on YOUR website! I need help listing the possible rational zeros of f(x)= 4x^3+12x^2-x+15, by using the rational zeros theorem. Could anyone help?
The rational zeroes are of the form a/b
The a must be a divisor of 15 such as +-1,+-3,+-5,+-15
The b must be a divisor of 4 such as +-1,+-2,+-4
List the various combinations of a and b; there are plenty.
