{\boxed{\underline{\tt{\orange{Required  \: Answer:-}}}}}

◉GIVEN:-

  • Quadratic equation:- kx( x-2)+6=0
  • (kx^2 - 2kx + 6 = 0)

◉TO FIND:-

  • Value of K

◉FORMULA USED:-

  • b^2 - 4ac = 0 (because this quadratic equation have two equal roots)

◉SOLUTIONS:-

Comparing the given equation with general equation ax^2 + bx + c = 0

We get,

  • a = k

  • b = -2k

  • c = 6

: \longrightarrow \sf{( { - 2k)}^{2}  - 4(k)(6) = 0} \\  \\ : \longrightarrow \sf{4 {k}^{2} - 24k = 0 } \\  \\ : \longrightarrow \sf{4k(k - 6) = 0} \\  \\  \sf{ \therefore \pink{ \: k = 0 \: and \: k = 6}}

HOPE IT HELPS :)
