a² - b² = (a - b)(a + b)
37*12,2+22,4²-14,6² = 37*12,2+(22,4-14,6)(22,4+14,6) = 37*12,2+7,8*37 = 37(12,2 +7,8) = 37*20 = 740
37*12,2+22,4²-14,6² = 740
a² - b² = (a - b)(a + b)
37*12,2+22,4²-14,6² = 37*12,2+(22,4-14,6)(22,4+14,6) = 37*12,2+7,8*37 = 37(12,2 +7,8) = 37*20 = 740
37*12,2+22,4²-14,6² = 740
