       can u guys show a case which a poly function won't be factored
       partially? like 3x^2+6x^2+7?

       3x^2+6x^2+7
       =9x^2+7
       now you can use the quadratic formula.

       I doubt Mr. Oh would put a function that we cannot factor, it'll
       make it harder for him too...
       so don't really worry about these function without real roots

       8. Solve each polynomial inequality by first finding the
       approximate zeros of the related polynomial function. Round
       answers to two decimal places.
       a) x²-6x-2>0
       b) -2x²-17x+3 >0
       c) x³+4x²-3x-16>0

       A and b you can use quadratic formual to find zeros. For c, camt
       do. So dont worry about polynomial inequality which is not
       factorable.

       Given S(x)=X^3 – 12x^2 + 36x, where x is the number of days and
       S(x) is number of sales. A profit is made if at least 10 sales
       are made. Use the equation to determine the number of days a
       profit was made. (Note: inequality question).

       It SAYS number of sales, s(x) is greater than 10, profit is
       made.
       So if s(x) > 10, then profit is made.
       Now it is straight fprward polynomial inequality.
