KnowledgeBoat · Accepted Answer

(x \+ 2) (x \+ 3) \+ (x \- 3) (x \- 2) \- 2x(x \+ 1) = 0 ⇒ x (x \+ 3) \+ 2 (x \+ 3) \+ x (x \- 2) \- 3 (x \- 2) \- 2x(x \+ 1) = 0 ⇒ x² \+ 3x \+ 2x \+ 6 \+ x² \- 2x \- 3x \+ 6 \- 2x² \- 2x = 0 ⇒ (x² \+ x² \- 2x²) \+ (3x \+ 2x \- 2x \- 3x \- 2x) \+ (6 \+ 6) = 0 ⇒ \- 2x \+ 12 = 0 ⇒ 2x = 12 ⇒ x = ⇒ x = 6 Hence, the value of x is 6.
