Answer:

$\alpha = - 3 \: , \: \beta = 4 \\ \blue{\mathfrak{\underline{\large{Using \: quadratic \: formula}}}:} \\ {x}^{2} - ( \alpha + \beta )x + \alpha \beta \\ =⟩ \: {x}^{2} - ( - 3 + 4)x + ( - 3) \times 4 \\ = ⟩ \: {x }^{2} - x - 12 \\ \blue{\mathfrak{\large{ \rightarrow \: correct \:answer \: is \: (a) }}} \\ \\ \red{\mathfrak{\underline{\large{Hope \: It \: Helps \: You }}}} \\ \green{\mathfrak{\underline{\large{Mark \: Me \: Brainliest}}}} \\ \blue{\mathfrak{\underline{\large{Have \: a \: nice \: day}}}}$
