I error in the problem was -x^2. This is the error because in order to find the negative real roots, every variable has to be changed into a negative. When three negatives are multiplied together, they still equal a negative. When two negatives are multiplied together, it becomes an positive sign. The third sign would be a negative because a positive multiplied by a negative equals a negative. This shows that the correct equation would be -x^3+x^2-x+1
