Answer :
By Transposition,
⇒ (x + 3)(2x – 3) = (x + 2)( 3x – 7)
⇒ 2x2 + 6x – 3x – 9 = 3x2 + 6x – 7x -14
⇒ 2x2 + 3x – 9 = 3x2 – x -14
⇒ 3x2 – 2x2 – x – 3x – 14 + 9 = 0
⇒ x2 – 4x – 5 = 0
⇒ x2 – 5x + x – 5 = 0
⇒ x(x – 5) + 1(x – 5) = 0
⇒ (x + 1)(x – 5) = 0
This gives 2 equations,
i. x + 1 = 0
⇒ x = -1
ii. x – 5 = 0
⇒ x = 5
Hence, x = -1 or x = 5
