A) (x + 5)(x + 6) / (x + 5)(x + 6) B) (x - 5)(x - 6) / (x - 5)(x - 6) C) (x + 3)(x + 10) / (x + 3)(x + 10) D) (x - 3)(x - 10) / (x - 3)(x - 10)
Show answer and explanation
Correct Answer

A. (x + 5)(x + 6) / (x + 5)(x + 6)

Explanation

The numbers 5 and 6 have product 30 and sum 11 so the factors are (x + 5)(x + 6).

5 और 6 का गुणनफल 30 और योग 11 है इसलिए गुणनखंड (x + 5)(x + 6) हैं।
