Answer»

Now in each of the pairs of polynomials given below, check whether the first is a factor of the second:



(i) x + 1, x3 − 1



(ii) x − 1, x3 + 1



(iii) x + 1, x3 + 1



(iv) x2 − 1, x4 − 1



(v) x − 1, x4 − 1



(vi) x + 1, x4 − 1



(vii) x − 2, x2 − 5x + 1



(viii) x + 2, x2 + 5x + 6



(ix)



(x) 1.3x − 2.6, x2 − 5x + 6
