যদি $σ - β = 8$ ও $σ^{3} - β^{3} = 152$ হয়, তবে $σ$ ও $β$ $x^{2} - 8 x - 12 = 0$ মূল বিশিষ্ট দ্বিঘাত সমীকরটি হলো -

x^{2} - 8 x - 12 = 0

x^{2} + 2 x - 15 = 0

x^{2} + 12 x + 15 = 0

x^{2} + 15 x + 2 = 0

x^{2} + 12 x + 8 = 0

X - \frac{9 x}{2 x^{2} + 18} + \frac{9}{4 x - 12} + \frac{9}{4 x + 12}

X + \frac{9 x}{2 x^{2} + 18} - \frac{9}{4 x - 12} - \frac{9}{4 x + 12}

X - \frac{9 x}{2 x^{2} + 18} - \frac{9}{4 x - 12} + \frac{9}{4 x + 12}

X - \frac{9}{2 x^{2} + 18} + \frac{9}{4 x - 12} + \frac{9}{4 x + 12}

X + \frac{9 x}{2 x^{2} + 18} + \frac{9}{4 x - 12} + \frac{9}{4 x + 12}
