Question 18735: P(X)=3X^3-10X^2-5X+2 HAS THREE REAL ROOTS ONE OF THEM IS -2/3 THE OTHERS ARE ____ AND ____
Answer by xcentaur(357)   (Show Source):
You can put this solution on YOUR website! Real roots implies that the value of the root will be greater than or equal to zero.
ie. say the root is x,then x>=0
As per the question,one of the three roots is -2/3
if all three roots are real,then (-2/3) cannot be one of the roots.
Please check your question and post again.

[Edit: The three roots (whether real or not) can be found by equating p(x) to zero and then solving the trinomial ]
