please write correct question is it not correct.
if you want to know the method how to solve these type of question then,question :find the value of 'a' if (x-1) is a factor of these equation 2(x^2)+ax+2=0.then first you know the value of x then you put the value of x and find the value of 'a' in this equation, So how to find the value x the (x-1) is a factor so is it satisfy the equation because it is a one of the factor of this equation.
(x-1)=0,x=1 so put x=1 in the equation
2(1^2)+a(1)+2=0
2(1)+a+2=0a+4=0a=-4hence proof
