Open in App
Solution

Let be the given polynomial.

Now, putting we get

f(1)=14-713+912+71-10=1-7+9+7-10=0

Therefore, is a factor of polynomial f(x).

Now,
f(x)=x4-x3-6x3+6x2+3x2-3x+10x-10

Where

Putting we get

Therefore, is a factor of g(x).

Now,
g(x)=x3-7x2+x2-7x+10x+10

From equation (i) and (ii), we get

Hence are the factors of polynomial f(x).
