$\large\boxed{ \fcolorbox{green}{yellow}{hope \: it \: help \: you}}$

Step-by-step explanation:

$\sf\pink{ {2x}^{2} - x - 6 = 0} \\ \sf\pink{ = > {2x}^{2} - 4x + 3x - 6 = 0 } \\ \sf\pink{ = > 2x(2x - 2) - 3(x - 2) = 0} \\ \sf\pink{ = > (x - 2)(2x - 3) = 0} \\ \sf\purple{x = 2 \: \: \: \: \: x = \frac{3}{2} } \\ \sf\pink{zeros \: = 2, \frac{3}{2} } \\ \sf\pink{here \: a = 2 \: \: \: b = \frac{3}{2} } \\ \sf\pink{ =(a - 1) + ( b- 1) } \\ \sf\pink{ = > 2 - 1 + \frac{3}{2} - 1} \\ \sf\pink{ = > 2 - 2 + \frac{3}{2} } \\ \sf\pink{ = > \frac{3}{2} }$
