Question

determine which of the following polynomials has x + 1 as factor x cube - x square - + 1​

Answer 1

Step-by-step explanation:

${x}^{3} - {x}^{2} - x + 1 \\ \\ {x}^{2} (x - 1) - 1(x - 1) \\ \\ ( {x}^{2} - 1)(x - 1) \\ \\ (x + 1)(x - 1)(x - 1)$

Therefore

x+1

is a factor of the polynomial
