expand (x-1+sqrt(3))(x-1-sqrt(3))

expand

(x - 1 + 3) (x - 1 - 3)

x^{2} - 2 x - 2

Solution steps

(x - 1 + 3) (x - 1 - 3)

Distribute parentheses

= xx + x (- 1) + x (- 3) - 1 \cdot x - 1 \cdot (- 1) - 1 \cdot (- 3) + 3 x + 3 (- 1) + 3 (- 3)

Simplify

xx + x (- 1) + x (- 3) - 1 \cdot x - 1 \cdot (- 1) - 1 \cdot (- 3) + 3 x + 3 (- 1) + 3 (- 3) : x^{2} - 2 x - 2

= x^{2} - 2 x - 2

\frac{x - 5}{( x + 1 ) ( x ^{2} - 2 x + 1 )}

\frac{( x + h ) ^{\frac{4}{3}} - x ^{\frac{4}{3}}}{h ( ( x + h ) ^{\frac{2}{3}} + x ^{\frac{2}{3}} )}

\frac{x ^{2} + 2 x - 9}{( 1 + x ) ^{2}}

\frac{1}{( s ^{2} + 1 ) ( s ^{2} + 2 s + 3 )}

- 3 (\frac{t}{81} + C)
