Question

x^4-2x^3-19x^2+49x-30 is divided by (x-1) (x-2) (x-3) then the quotient​

Answer 1

Answer:

Let f(x)= x^4-x^3-19x^2+49x-30

We find the first factor generally by hit and trial method

Put x=1

f(1)= 1-1-19+49-30=0

So (x−1) is a factor of f(x).

Hope this is helpful.

Answer 2

Answer :

let f ( x ) = x^4 - x^3 - 19 x^2 + 49 x - 30

we find the first factor generally by hit

and trial method

put x = 1

f ( 1 ) = 1 - 1 - 19 + 49 - 30 = 0

so ( x - 1 ) is a factor of f ( x )
