(\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta). Here (\left\(-\frac{7}{6}\right\)2-2\cdot\frac{1}{3}=\frac{25}{36}).
Step 2
Why this answer is correct
The correct answer is A. \( \frac{25}{36} \). (\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta). Here (\left\(-\frac{7}{6}\right\)2-2\cdot\frac{1}{3}=\frac{25}{36}).
Step 3
Exam Tip
(\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta) होता है। यहाँ (\left\(-\frac{7}{6}\right\)2-2\cdot\frac{1}{3}=\frac{25}{36})।
(\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta). Here (\left\(-\frac{6}{5}\right\)2-2\cdot\frac{1}{5}=\frac{26}{25}).
Step 2
Why this answer is correct
The correct answer is A. \( \frac{26}{25} \). (\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta). Here (\left\(-\frac{6}{5}\right\)2-2\cdot\frac{1}{5}=\frac{26}{25}).
Step 3
Exam Tip
(\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta) होता है। यहाँ (\left\(-\frac{6}{5}\right\)2-2\cdot\frac{1}{5}=\frac{26}{25})।
If the roots are \(\alpha,\beta\), then (\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta). Here (\left\(-\frac{8}{3}\right\)2-2\cdot\frac{4}{3}=\frac{40}{9}).
Step 2
Why this answer is correct
The correct answer is A. \( \frac{40}{9} \). If the roots are \(\alpha,\beta\), then (\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta). Here (\left\(-\frac{8}{3}\right\)2-2\cdot\frac{4}{3}=\frac{40}{9}).
Step 3
Exam Tip
यदि मूल \(\alpha,\beta\) हैं, तो (\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta)। यहाँ (\left\(-\frac{8}{3}\right\)2-2\cdot\frac{4}{3}=\frac{40}{9})।
If the roots are \(\alpha,\beta\), then (\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta). Here (\left\(-\frac{7}{2}\right\)2-2\cdot\frac{3}{2}=\frac{37}{4}).
Step 2
Why this answer is correct
The correct answer is A. \( \frac{37}{4} \). If the roots are \(\alpha,\beta\), then (\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta). Here (\left\(-\frac{7}{2}\right\)2-2\cdot\frac{3}{2}=\frac{37}{4}).
Step 3
Exam Tip
यदि मूल \(\alpha,\beta\) हैं, तो (\alpha-2+\beta-2=\(\alpha+\beta\)2-2\alpha\beta)। यहाँ (\left\(-\frac{7}{2}\right\)2-2\cdot\frac{3}{2}=\frac{37}{4})।
