- anonymous

there has been a mistake mate . it was A(-6,0)
sorry for that

- anonymous

yeah but I didnt understand that part how you found the radius

- anonymous

ohhh ok you mean its from the centre

- anonymous

right ?

- anonymous

ok so OB is 2 with pythagoras it will be

- anonymous

just one more question

- anonymous

the answer will be root 21

- anonymous

but why the 90 degree became what you called as B ?

Yoou mean because of the tangent

I will delete the previous problem to save the time to scroll down, ok?

- anonymous

ok
The remainders when a polynomial P(x) is divided by x-2 and x+1 are respectively 3 and -2. The remainder when P(x) is divided by (x^2-x-2)is K(x). What is the value of K(-4) ?

- anonymous

Did you get the question ?

- Loser66

Yes, I am thinking.

- anonymous

ok.

- anonymous

anything :D

- Loser66

I don't know.

- anonymous
