Hey there !!
▶ The given quadratic equation :-
=> 4x² + 4bx = ( a² - b² ) .
[Adding b² on both side ]
=> 4x² + 4bx + b² = a² - b² + b² .
=> (2x)² + 2 × 2x × b + b² = a² .
=> ( 2x + b )² = a² .
[ Taking square root on both side, we get ] .
=> 2x + b = ± a.
=> 2x + b = a or 2x + b = -a .
=> 2x = a - b or 2x = - a - b .
✔✔ Hence, it is solved ✅✅.
