how can -6 be cancelled by -6
it can be cancelled only when there is one sign of (+) and other of (-)... and numerical value should be same

(x-1)(x+6)- (x-2)(x-3) =3
=> x²-x +6x-6 - [ x²-3x-2x+6] = 3
=> x² +5x -6 - [ x² - 5x +6] = 3
=> x² +5x -6 - x² +5x -6 = 3
=> 10x - 12 = 3
=> 10x= 3+12
=> x= 15/10
=> x = 3/2
=> x = 1.5
=> x²-x +6x-6 - [ x²-3x-2x+6] = 3
=> x² +5x -6 - [ x² - 5x +6] = 3
=> x² +5x -6 - x² +5x -6 = 3
=> 10x - 12 = 3
=> 10x= 3+12
=> x= 15/10
=> x = 3/2
=> x = 1.5
