Q. 1 C5.0( 1 Vote )

Determine which of the following polynomials has (x – 1) a factor?

x4 + 3x3 – 3x2 + x – 2

Answer :

We know that (x – 1) will be the factor of the polynomial if by substituting x = 1 in polynomial we get the zero remainder.

by putting x = 1 in x4 + 3x3 – 3x2 + x – 2, we get -


14 + 3(1)3 – 3(1)2 + 1 – 2 = 1 + 3 – 3 + 1 – 2


= 0


(x – 1) is a factor of x4 + 3x3 – 3x2 + x – 2
