Question

8. (x2 - 1) (x + 1) (x + 2)(x – 4)​

Answer 1

Answer:

Step-by-step explanation:

 (x2 - 1) (x + 1) (x + 2)(x – 4)​

=2x(x+1)-1 (x + 1)  (x + 2)(x – 4)​

=(2x²+2x-x-1) (x + 2)(x – 4)​

=x(2x²+2x-x-1)+2(2x²+2x-x-1) (x-4)

=2x³+2x²-x²-x+4x²+4x-2x-2 (x-4)

=2x³+5x²+5x-2 (x-4)

=x(2x³+5x²+5x-2)-4(2x³+5x²+5x-2)
