⇒ (2x+ 4)(x − 2) = (2x − 11)(x+ x − 2)

⇒ 2x− 4x+ 4x − 8 = 2x+ 2x− 4x − 11x− 11x + 22

⇒ 2x− 4x+ 4x − 8 = 2x− 9x− 15x + 22

⇒ 2x− 2x− 4x+ 9x+ 4x + 15x − 8 − 22 = 0

⇒ 5x+ 19x − 30 = 0

⇒ 5x+ 25x − 6x − 30 = 0

⇒ 5x(x + 5) − 6(x + 5) = 0

⇒ (5x − 6)(x + 5) = 0

⇒ 5x − 6 = 0, x + 5 = 0

⇒ x = 6/5, x = −5
