How to find the set of values of P(x) = 3x³ + 29x² + 65x - 25 given that (x+5) is a repeated factor and (3x - 1) is the third factor and P(x) > 0? It seems like easy because the original question was about finding the factors and as you can see, I've found them so you guys don't need to waste time finding them. The thing I'm confused about now is how to get the set values? My answer was -5 < x < 1/3 but the answer they gave is x > 1/3.

P.s., if my answer is in the wrong section, please notify me as soon as possible but I'm sure its in the correct section because it does not involves differentiation and I've searched and found that many questions of set values are under pre-calculus.
