### The solution for August 17th

The solution for August 17th

Is the solution wrong? I checked and the numerator does not have root 3. It seems the function does not have any minimum value

Re: The solution for August 17th

Hi Victoria. Thanks for pointing this out! In fact the problem was meant to have $x^3+3x^2-10x - 24$ (with $-24$ instead of $+24$). Then things work out nicely (with the polynomial division having no remainder). The question and solution are now updated.

Please let us know if you have any other questions!
