Răspuns :
a² - b² = (a + b) ( a - b)
(a + b) × 2√2 = 24
a + b = 24 : 2√2
a + b = 12/√2
a + b = 12√2/2
a + b = 6√2
(a + b) × 2√2 = 24
a + b = 24 : 2√2
a + b = 12/√2
a + b = 12√2/2
a + b = 6√2
a-b = 2√2
a² - b² = 24
(a-b)(a+b)=24
2√2(a+b)=24
a+b=24 / 2√2
a+b=12/√2
a+b=6√2
a² - b² = 24
(a-b)(a+b)=24
2√2(a+b)=24
a+b=24 / 2√2
a+b=12/√2
a+b=6√2
