Find the value of k for which one root of the quadritic equation kx2-14x+8=0 is 2 |
|
Answer» Sorry it\'s k = 5 as ........28 - 8 = 20 nd.....,,,, 4k - 20=0 ......so,,,,,, k= 20/4=5 hence the value of k =5 x =2 so ,,,,_______ k(2^2) - 14^2 + 8 = 4k - 36=0 ,,,,,,,, 4k =36 = k =36/4 = 9 ...........so the value of k = 9 K=5 |
