Question

plz factorise this........

Answer 1

HEYA !

x³ - x² + ax + x - a - 1

= x² (x - 1) + x(a + 1) - 1(a + 1)

= x²(x - 1) + (a + 1) (x - 1)

= (x - 1) (x² + a + 1)

Answer 2

Change their places
So
X³-x²+ax-a+x-1
Take the common
So
X²(x-1)+a(x-1)+1(x-1)
So
Answer is
(X²+a+1)(x-1)







I hope this will helpyou
