Answer 2

Answer:-

(1) Almost three zeroes--(3)

$(3) \: \alpha + \beta = - 7 \\ \: \: \: \: \: \: \: \: \: \: \: \: \alpha \beta = - 8 \\ {x}^{2} - ( \alpha + \beta )x + \alpha \beta \\ = {x}^{2} + 7x - 8$

$(4)a {x}^{2} - 9x + 15 \\ \\ \alpha \beta = - 6 \\ \\ \alpha \beta = \frac{ c}{a} \\ \\ - 6 = \frac{15}{a} \\ \\ a = \frac{ 15}{6} \\ \\ a = \frac{ 3}{2}$
