Answer» A² = b + c b² = c + ac² = a + b a² - b² = b - a => (a - b) (a + b) = b - a => a + b = -1 or a = b 1) a + b ≠ - 1 as c² is not negative, if c is a real number. a = b => c² = 2 a similarly, b = c => a² = 2 b (as b+c ≠ -1, as a² is non negative) and c = a => b² = 2 a so we get a = b = c = 2 1/1+a + 1/1+b + 1/1+c = 1/3 + 1/3 + 1/3 = 3/3 = 1 Like my answer if you find it useful! |
