If `` M '' is simplified ( that is , `` B '' = `` C '' = 0 ) , you can use the diagonal formula . If `` M '' is simplified ( that is , `` B '' = `` C '' = 0 ) , one can use the diagonal formula .
Jika "M" 'dimudahkan (iaitu, "B"'= "C"'= 0), anda boleh menggunakan formula pepenjuru. Jika "M" 'dimudahkan (iaitu, "B"' = "C"' = 0), seseorang boleh menggunakan formula pepenjuru.
