Answer 2

Step-by-step explanation:

Values on the frontside of the card

$\alpha = 6 \\ \beta = - 3 \\ \alpha + \beta = 6 + ( - 3) \\ = 6 - 3 \\ = 3 \\ \alpha \beta = 6 \times - 3 \\ = - 18 \\ so \: quadratic \: equation \: = {x}^{2} - ( \alpha + \beta )x + \alpha \beta \\ = {x}^{2} - (3)x + ( - 18) \\ = {x}^{2} - 3x - 18$

values on the backside of the card

$\alpha = - 6 \\ \beta = 7 \\ \alpha + \beta = - 6 + 7 \\ = 1 \\ \alpha \beta = - 6 \times 1 \\ = - 6 \\ so \: quadratic \: equation \: = {x}^{2} - ( \alpha + \beta )x + \alpha \beta \\ = {x}^{2} - (1)x + ( - 6) \\ = {x}^{2} - 1x - 6$
