AT FIRST. do u know what a degree of polynomial means.

\[3x^3+(3x^2/2)−(3x/2)+(3/2)\]
is this correct?

for 1.?

simplify that.

Is my answer correct?

|dw:1343207441484:dw|

how about for no. 2 could you help me?

can u simplify this plz

I DONT THINK YOUR ANSWER IS CORRECT.

ok

FOR NUMBER 2)
do u know factor theorem

could I make \[(x-1/2) -------> (2x-1)\] ????????

|dw:1343207772794:dw|

NOW do u know factor theorem?
and did u get answer for 1)

\[3x^3-(3x^2/2)−3x−(3/2)\]

am I correct now?

NOPE.

BUT U R VERY CLOSE

I'll do it again :)

u just made the sign mistake

could I make (x-1/2) into (2x-1)
because my teacher said there should be no fractions?

|dw:1343208282102:dw|

is the correct answer

could I make (x-1/2) into (2x-1) ??????

NOPE because|dw:1343208355724:dw|

but if |dw:1343208386811:dw|

that's what I mean for the second part

because|dw:1343208443188:dw|

isn't that it is zero so that it is possible?

|dw:1343205903760:dw|

IF it is equal to zero then yes u can because |dw:1343208534245:dw|

|dw:1343205945423:dw|

so what?

I got the correct answer :)

and what is that

it mean that there zeroes are both 1/2

so you can use either of the two?

yeah. BUT only in that case. U cannot use this in simplification.

AND NOW SHALL WE BEGIN NO. 2

yup :)

do u know factor theorem.

wait I am trying to solve 1 with (2x-1) :)

I got the same answer :)

is that correct?
could you improve my definition of factor ?

No u r defination is correct. And can u use this to solve this problem

how
I am confused with the question?

I am thinking of distributing -3 to x

but I can't explain why it is correct :)

ohh, I think it also has remainder theorem? :)

YEAH.

now can u

|dw:1343207190855:dw|

I added =0 so that the remainder will be equal to zero making (x+3) a product ?

solve for k

am I correct with my reason?

yeah

k=1/2

@sauravshakya thank you very much for your help :)

U r WELCOME. AND best of luck
