Answer 1

Answer:

$\underline{\sf\huge \implies:(x - 1)(x + 2) } \: \: \: \ddot \smile$

Step-by-step explanation:

$\sf\pink{ \bigstar \: \: {x}^{2} + x - 2} \\ \\ \underline{\bf\red{using \: splitting \: the \: middle \: term \: method}} \\ \\ \sf\ \implies: {x}^{2} + (2x - x) - 2 \\ \\ \sf\ \implies: {x}^{2} + 2x - x - 2 \\ \\ \sf\ \implies:x(x + 2) - 1(x + 2) \\ \\ \boxed{\sf\ \implies:(x - 1)(x + 2) }$
