Shorten the Controller Logic Laravel

Question

I'm trying using Laravel login authentication using different guards but I found that there is some repetition within the store method in the Login Controller (the only difference is the guard used, all other logic are the same). I just can't find a way to shorten them into some other logic such as method(function) which can be reusable. So if there is possible way, Please help me out.

 public function store(Request $request)
{

    $request->validate([
        'username' => 'required',
        'password' => 'required'
    ]);


    if (Auth::guard('instructor')->attempt(['email' => $request->username, 'password' => $request->password])) {

        if (auth('instructor')->user()->status === Instructor::HAS_DEACTIVATED) {
            $request->session()->flush();
            Auth::guard('instructor')->logout();
            return redirect('login')->with(
                'error',
                'Your Account has being deactivated . Please Contact your Administrator!');
        }

        return redirect(route('instructor.dashboard'));


    }
    if (Auth::guard('student')->attempt(['email' => $request->username, 'password' => $request->password])) {

        if (auth('student')->user()->status === Student::HAS_DEACTIVATED) {
            $request->session()->flush();
            Auth::guard('student')->logout();
            return redirect('login')->with(
                'error',
                'Your Account has being deactivated . Please Contact your Administrator!');
        }
        return redirect(route('student.dashboard'));
    }
    return back()->with('error', 'Credentials provided do not match any record.');

}

This is probably not the best way to go about this, I'm sure there is a better solution, and @Aqib Javaed's seems to be it, but here's one way to shorten the code a bit that I could manage. It's not perfect but does the job done.

public function store(Request $request)
{

    $request->validate([
        'username' => 'required',
        'password' => 'required'
    ]);

    if (Auth::guard('instructor')->attempt(['email' => $request->username, 'password' => $request->password])) {
        $userType = 'instructor';
    } elseif (Auth::guard('student')->attempt(['email' => $request->username, 'password' => $request->password])) {
        $userType = 'student';
    } else {
        return back()->with('error', 'Credentials provided do not match any record.');
    }

    $modelName = ucwords($userType); //turn the user type to its corresponding model name
    if (auth('$userType')->user()->status === $modelName::HAS_DEACTIVATED) {
        $request->session()->flush();
        Auth::guard('$userType')->logout();

        return redirect('login')->with(
            'error',
            'Your Account has being deactivated . Please Contact your Administrator!');
    }

    return redirect(route("$userType.dashboard"));
}
