Answer
-5x^2+5
Step-by-step explanation:
(2x-3)^2-(3x-2)^2
=4x^2-12x+9-(9x^2-12x+4)
=4x^2-12x+9-9x^2+12x-4
=4x^2+9-9x^2-4
=-5x^2+5
❍ Correct Question:-
- (2x - 3)² - (3x - 2)²
❍ Solution:-
Given, To Factorise
➝ (2x - 3)² - (3x - 2)²
Opening the parentheses,
➝ (4x² - 12x + 9) - (9x² - 12x + 4)
➝ 4x² - 12x + 9 - 9x² + 12x - 4
Arranging the like terms,
➝ 4x² - 9x² - 12x + 12x + 9 - 4
➝ -5x² + 5
➝ -5(x² - 1)[tex].[/tex]
[ Identity :- (a² - b²) = (a + b)(a - b) ]
➝ -5(x² - 1²)
➝ -5(x + 1)(x - 1)
☘ Hence, Factorised !!
