यदि \([t]\) महत्तम पूर्णांक \(\leq t\) है, तो \(\int_0^1\left[2 x-\left|3 x^2-5 x+2\right|+1\right] d x\) का मान है-

  1. A \(\frac{\sqrt{37}+\sqrt{13}-4}{6}\)
  2. B \(\frac{\sqrt{37}-\sqrt{13}-4}{6}\)
  3. C \(\frac{-\sqrt{37}-\sqrt{13}+4}{6}\)
  4. D \(\frac{-\sqrt{37}+\sqrt{13}+4}{6}\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(\frac{\sqrt{37}+\sqrt{13}-4}{6}\)

Step-by-step Solution

Detailed explanation

\(I=\int \limits_{0}^{1}\left[2 x-\left|3 x^{2}-3 x-2 x+2\right|+1\right] d x\) \(I=\int \limits_{0}^{1}[2 x-|(3 x-2)(x-1)|] d x+\int_{0}^{1} 1 d x\)…
