(u² - 4v²)/2uv : (1/2v - 1/u) = (u - 2v)(u + 2v)/2uv : (u - 2v)/2uv = u + 2v
при u = 8 1/17; v = 13 8/17 получим: 8 1/17 + 2 · 13 8/17 =
= 8 1/17 + 26 16/17 = 34 17/17 = 35

смотри фото, там решение
(u² - 4v²)/2uv : (1/2v - 1/u) = (u - 2v)(u + 2v)/2uv : (u - 2v)/2uv = u + 2v
при u = 8 1/17; v = 13 8/17 получим: 8 1/17 + 2 · 13 8/17 =
= 8 1/17 + 26 16/17 = 34 17/17 = 35
