1. Find the products : (x - 1) (x + 1) (x + 1) (x + 1)​

Answer 1

Answer :

Now, (x - 1) (x + 1) (x + 1) (x + 1)

= (x - 1) {(x + 1) (x + 1) (x + 1)}

= (x - 1) (x + 1)³

= (x - 1) (x³ + 3x² + 3x + 1)

= x (x³ + 3x² + 3x + 1) - 1 (x³ + 3x² + 3x + 1)

= x⁴ + 3x³ + 3x² + x - x³ - 3x² - 3x - 1

= x⁴ + 2x³ - 2x - 1 ,

which is the required production.
