Find ab bc ca Login Remember Register;Solution Verified by Toppr Consider, a 2b 2c 2–ab–bc–ca=0 Multiply both sides with 2, we get 2(a 2b 2c 2–ab–bc–ca)=0 ⇒ 2a 22b 22c 2–2ab–2bc–2ca=0 ⇒ (a 2–2abb 2)(b 2–2bcc 2)(c 2–2caa 2)=0 ⇒ (a–b) 2(b–c) 2(c–a) 2=0 SinceBài 7 Một ô tô đi từ tỉnh A đến tỉnh B với một vận tốc đã địnhNếu vận tốc tăng thêm km/h thì thời gian đi được sẽ giảm 1 giờ Nếu vận tốc giảm bớt 10 km/h thì thời gian đi sẽ tăng thêm 1 giờ Tính vận tốc và thời gian dự định của ô tô Bài 8 Hai địa điểm A và B cách nhau 85 km
This inequality can be solved by simple algebra we have the equation a 2 b 2 c 2 >= a b a c c b multiply and divide 2 on both sides 2 2 ( a 2 b 2 c 2) >= 2 2 ( a b a c c b) putting the left side equation on the right side 2 a 2 2 b 2 2 c 2 − 2 ( a b a c c b) 2 >= 0`(abc)^2 = a^b^2 c^2 2(ab bc ca)` Given that `a^2 b^2 c^2 = ` `(abc) = 0` Then we have `(abc)^2 = a^2 b^2 c^2 2 (ab bc ca)` `(0)^2 = 2(ab bc ca)` ` if a2 b2 c2 90 and a b c then find the value of ab bc ca Mathematics TopperLearningcom w9sw2x377 if a2 b2 c2 90 and a b c then find the value of ab bc ca Mathematics TopperLearningcom w9sw2x377 Starting early can help you score better!
