Question

if 2 is zeroes of polynomial x²-km+6 then value of k= ?​

Answer 1

Answer:

k = 5

Step-by-step explanation :

$given \ polynomial, \\ p(x)=x^{2}-kx+6 \\\\ 2 \ is \ zero \ of \ the \ polynomial. \\ .'. \ p(2)=0 \\\\=> 2^{2}-2k+6=0 \\=>4-2k+6=0\\=>10-2k=0\\=>2k=10\\=>k=\frac{10}{2} \\=>k=5$
