Find the value of k , x=a is a solution of equation x×x (a+b)x+k=0 |
| Answer» We have, x2- x (a+b) + k = 0Since x = a is the solution of the given equation.{tex}\\therefore{/tex}\xa0x = a satisfies the given equation.a2- a (a+b) + k = 0{tex}\\implies{/tex}a2 - a2 -ab +k = 0{tex}\\implies{/tex}k - ab = 0 or k =ab | |
