Q1) Find the values of 'a'so that (-2) is a roots of 2x²-x+a=0

$\: \: \underline{ \boxed{ \sf{ \color{magenta} \: answer \to}}}$

$\: \: \implies \bf{2 {x}^{2} - x + a = 0}$

$\: \: \implies \displaystyle \tt{2 {( - 2)}^{2} - ( - 2) + a = 0}$

$\: \implies \displaystyle \tt{8 + 2 + a = 0}$

$\: \: \implies \displaystyle \bf{a = - 10}$
