The value of k, for which one root of the quadratic equation kx2 -14x +8 =0 is six times the other. |
|
Answer» Answer: Let a root be r. Then other root is 6r Then, r+6r = - (-14)/K and r.6r = 8/k Hence, 7r = 14/k i.e r = 2/k So, 6.(2/k)^2 = 8/k => 24/(k^2) = 8/k => k = 3 Step-by-step explanation: Putting k you get the roots as 4 and 2/3 which are the roots of the equation. ALSO, 4 is 6 TIMES that of 2/3 |
