expand (x+1)(x-1)(x^2+1)

expand

(x + 1) (x - 1) (x^{2} + 1)

x^{4} - 1

Solution steps

(x + 1) (x - 1) (x^{2} + 1)

Expand

(x + 1) (x - 1) (x^{2} + 1) : (x^{2} - 1) (x^{2} + 1)

= (x^{2} - 1) (x^{2} + 1)

Apply Difference of Two Squares

(x^{2} - 1) (x^{2} + 1) : x^{4} - 1

= x^{4} - 1

x - (12 - 5 x)

- a - b

(3^{2}) (3^{4})

\frac{- 2}{10}

\frac{6}{2 x ^{2}} + \frac{5}{2 x ^{2}}
