Question

if (x-2) is a factor of xcube-3xsq+k,then find k​

Answer 1

Answer:

k=4

Step-by-step explanation:

x-2 is a factor therefore put x=2 in the given equation

2x2x2 -3x2x2+k,=0

8-12+k=0

-4+k=0

k=4

Answer 2

Answer:

[ x = 2 ]

x^3 - 3x^2 + k

( 2 ) ^3 - 3 * ( 2 ) ^2 + k

8 - 3 * 4 + k

8 - 12 + k

- 4 + k

k = 4
