✏Solution :-
ax² +a = a² +x
=> ax² - x +(a+a²)=0
=> x = [ 1 ± √ {1² -4×a×(a+a²)}]/2a
=>x = [ 1± √ { 1 - 4a² - 4a³} ]/2a
=> x = [ 1±√(1-4a³-4a²)]/2a
take first +ve sign and negative ,
✏you can find your roots .

Answer:
The given equation is:
ax^2 + a = a^2 + x
ie. ax^2 + a - a^2 - x = 0
=> ax^2 - a^2 + a - x = 0
=> ax(x - a) - (x - a) = 0
=> (x - a)(ax - 1) = 0
Now , if (x - a) = 0
then , x = a.
And, if ( ax - 1) = 0
then, x = 1/a.
Hence, the required roots of the given equation are: a and 1/a.
