How to compare two encrypted(bcrypt) password in laravel

if(Hash::check('plain-text-password',$cryptedpassword)) {
    // Right password
} else {
    // Wrong one
}

You can simply use Hash::check() method eg:

if(Hash::check('plain-text', $hashedPassword)) {
    return true;
}

reference https://laravel.com/docs/5.5/hashing

You can't actually compare two encrypted bcrypt passwords to each other directly as strings because the encryption contains salt which makes the hashes different each time.
