7 + 3√5 / 3 +√5 - 7 - 3√5 / 3 - √5 = a -b√5
6 + 2√5 - (6 - 2√5) / (3 +√5)(3 - √5) = a - b√5
6 +2√5 - 6 + 2√5 / 9 - 5 = a - b√5
4√5 / 4 = a - b√5
√5 = a -b√5
squaring both sides,
(√5)² = (a - b√5)²
5 = a² - b² * 5
5/5 = (a+b)(a-b)
1 = (1+0)(1-0)
1 = 1 * 1
1 = 1
(verified)
Hence a =1 and b = 0
HOPE IT'S RIGHT.
