help please (((: fan and medal <3 find any rational roots? 1. p(x) = 3x^3 - x^2 -7x + 2 2. p(x) = x^3 + 5x^2 + x + 5

OpenStudy (faiqraees):

Use trial and error to find the first root, divide the equation by the discovered root and then use the quadratic formula to find the next two roots. The one which doesn't contain an imaginary number is the rational root.
