JEE Mains · Maths · STD 11 - 4.2 Quadratic equations and inequations

यदि \(\alpha\) तथा \(\beta\), समीकरण \(x ^{2}+(3)^{1 / 4} x +3^{1 / 2}=0\) के दो भिन्न मूल हैं, तो \(\alpha^{96}\left(\alpha^{12}-1\right)+\beta^{96}\left(\beta^{12}-1\right)\) का मान बराबर है

  1. A \(56 \times 3^{25}\)
  2. B \(52 \times 3^{24}\)
  3. C \(56 \times 3^{24}\)
  4. D \(28 \times 3^{25}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(52 \times 3^{24}\)

Step-by-step Solution

Detailed explanation

As, \(\left(a^{2}+\sqrt{3}\right)=-(3)^{1 / 4} \cdot \alpha\) \(\Rightarrow\left(\alpha^{2}+2 \sqrt{3} \alpha^{2}+3\right)=\sqrt{3} \alpha^{2} \text { (On squaring) }\) \(\left.\therefore\left(a^{4}+3\right)=(-) \sqrt{3} \alpha^{2}\right)\)…
