Answer:

60 seats are vacant dear

Answer 2

Step-by-step explanation:

$2x^{2} - 3x - 6 \: \\ a \: and \: b \: are \: zeroes \\ a + b = \frac{- ( - 3)}{2} = \frac{ 3}{2} \\ a \times b = \frac{ - 6}{2} = - 3 \\ \\ \frac{1}{a} + \frac{1}{b} = \frac{a + b}{ab} = \frac{3}{2} \times \frac{1}{ - 3} = - \frac{1}{2} \\ \\ \frac{1}{a} \times \frac{1}{b} = \frac{1}{ab} = \frac{1}{ - 3} \\ \\ equation = = > > {x}^{2} - ( \frac{1}{a} + \frac{1}{b} ) + \frac{1}{ab} \\ \\ {x}^{2} + \frac{1}{2} - \frac{1}{3} = 0 \\ \\ 6 {x}^{2} + 3x - 2 = 0$
