Answer:

x= -a and x= 0.5a

Step-by-step explanation:

2x²+ ax - a² = 0

the standard quadratic equation is in form of

ax²+bx=c

and formula to find its roots is

x = (-b±√(b²-4ac))/(2a)

so putting values of our equation in the formula

x = (-a±√(a²+8a²))/4

x = (-a±√(9a²))/4

x = (-a±3a)/4

x = -a

and

x = 0.5a
