Answer 1

$\huge\purple{Required \: Answer :}$

Given :

$(x + 1)(x + 2) = (x + 1)(x - 2)$

Solution :

$(x + 1)(x + 2) = (x + 1)(x - 2) \\ {x}^{2} + 2x + x + 2 = {x}^{2} - 2x + x - 2 \\ {x}^{2} + 3x + 2 = {x}^{2} - x - 2 \\ 3x + x + 2 = {x}^{2} - {x}^{2} - 2 \\ 4x + 2 = - 2 \\ 4x = - 2 - 2 \\ 4x = - 4 \\ x = \frac{ - 4}{4} \\ x = - 1$

$\huge{x = -1}$
