Question 254242: 3x2 plus kx plus 4 divided by x-2=3x-2 then k= , if x= (with a slash mark going thru = sign) Found 2 solutions by MRperkins, drk:Answer by MRperkins(300) (Show Source):
You can put this solution on YOUR website! WHat we have is =3x-2 then k= ?
It appears you have don the division or have been told the answer.
If we divide synthetically, then we get
2 / . . 3 . . . . k . . . . .4
. . . . . . . . .6 . . . . .2k + 12
. . . . 3 . . . . k+6 . . . .0
This means that 2k + 16 = 0 or k = -8.
If k = -8, then k + 6 = -2 and the quotient is
3x - 2.
Now we have a restriction on the domain; x - 2 not = 0 which means x not = 2.
Hope this makes sense.
