Basic Math Formula (a − b)² = a² − 2ab b² a² − b² = (a b)(a − b) (a b)² = a² 2ab b² (a − b)² = (a b)² − 4ab (a b)² = (a − b)² 4ab a² b² = (a − b)² 2ab a² b² = (a b)² − 2ab 4ab = (a b)² − (a − b)² ab = (a b)²/4 − (a − b)²/4 = {(a b)/2}² − {(a − b)/2}² #basicmath #school, #algebra #formulas #reelsviralシ | Satt Academy
