Step-by-step explanation:

QUESTION :-

(3x² - 5x - 3) - (x² - 5x + 6) = ?

1. (2x² - 9)
2. (x² + 9)
3. (2x² - 10x + 9)
4. (2x² - 10x - 9)

SOLUTION :-

(3x² - 5x - 3) - (x² - 5x + 6)

=> 3x² - 5x - 3 - x² + 5x - 6

=> 3x² - x² + 5x - 5x - 3 - 6

=> 2x² - 9

Hence,

The answer is (2x² - 9) {option (1)}.
