a²-b²=24
a-b=2√2
(a-b)*(a+b)=24
2√2*(a+b)=24
a+b=24/2√2
a+b=12/√2
a+b=12√2/2
a+b=6√2
a-b=2√2
(a-b)*(a+b)=24
2√2*(a+b)=24
a+b=24/2√2
a+b=12/√2
a+b=12√2/2
a+b=6√2
a² - b² = (a + b) ( a - b) = 24
(a + b) x 2√2 = 24
a + b = 24 /2√2
a + b = 12/√2 = 12√2/2
a + b = 6√2
(a + b) x 2√2 = 24
a + b = 24 /2√2
a + b = 12/√2 = 12√2/2
a + b = 6√2
