Correct Question :- From the sum of 3x² - 5x + 2 , -5x²- 8x + 9 and subtract 4x² - 7x + 9. ?
Solution :-
→ {(3x² - 5x + 2) + (-5x²- 8x + 9)} - (4x² - 7x + 9)
→ (3x² - 5x² - 5x - 8x + 2 + 9) - (4x² - 7x + 9)
→ (-2x² - 13x + 11) - (4x² - 7x + 9)
→ - 2x² - 4x² - 13x + 7x + 11 - 9
→ (- 6x² - 6x + 2 ) (Ans.)
