✨✨HEY DEAR HERE IS YOUR ANSWER ✌✌❤❤

---------------------------------------------------------------
---------------------------------------------------------------

➡ GIVEN POLYNOMIAL f (x) IS :-

= 5x3 – 10x2k – 3x – 6.

Since, (x – 2k) is a factor of f(x).

∴ f (2k) = 0

⇒ 5(2k)3 – 10(2k)2k – 3(2k) – 6 = 0

⇒ 40k3 – 40k3 – 6k – 6 = 0

⇒ –6k = 6

⇒ k = 6/ -6 = - 1

➡ SO THE VALUE OF K = -1 .
