x² + 5x + 6 और x² + 4x + 4 का लघुतम समापवर्त्य है
  1. Ax + 2x + 2
  2. B(x + 2)(x + 3)(x + 2)(x + 3)
  3. C(x + 2)(x + 2)(x + 3)(x + 2)(x + 2)(x + 3)
  4. DMore than one of the aboveउपर्युक्त में से एक से अधिक
  5. ENone of the aboveउपर्युक्त में से कोई नहीं
Show answerHide answer

Correct answer: (C) (x + 2)(x + 2)(x + 3)(x + 2)(x + 2)(x + 3)

Explanation

x² + 5x + 6 = (x + 2)(x + 3) and x² + 4x + 4 = (x + 2)², so the LCM is (x + 2)²(x + 3).x² + 5x + 6 = (x + 2)(x + 3) और x² + 4x + 4 = (x + 2)², अतः ल॰स॰ = (x + 2)²(x + 3)।
