1.Suppose the cubic x3−px+qx^3 - px + qx3−px+q has three distinct real roots where p>0p > 0p>0 and q>0q > 0q>0. Then which one of the following holds?a.The cubic has minima at p/3\sqrt{p/3}p/3 and maxima at −p/3-\sqrt{p/3}−p/3b.The cubic has minima at −p/3-\sqrt{p/3}−p/3 and maxima at p/3\sqrt{p/3}p/3c.The cubic has minima at both p/3\sqrt{p/3}p/3 and −p/3-\sqrt{p/3}−p/3d.The cubic has maxima at both p/3\sqrt{p/3}p/3 and −p/3-\sqrt{p/3}−p/3Login to continueOnly logged in users canattempt or see the solution.
