simplify (x-1-sqrt(5))(x-1+sqrt(5))

simplify

(x - 1 - 5) (x - 1 + 5)

x^{2} - 2 x - 4

Solution steps

(x - 1 - 5) (x - 1 + 5)

Distribute parentheses

= xx + x (- 1) + x 5 - 1 \cdot x - 1 \cdot (- 1) - 1 \cdot 5 - 5 x - 5 (- 1) - 55

Simplify

xx + x (- 1) + x 5 - 1 \cdot x - 1 \cdot (- 1) - 1 \cdot 5 - 5 x - 5 (- 1) - 55 : x^{2} - 2 x - 4

= x^{2} - 2 x - 4

(7 - 2 i)^{5}

(- 3 + \frac{3 i}{n})^{2}

\frac{3 ( x + h ) ^{2} - 1 - 3 x ^{2} - 1}{h}

(2 + i)^{10}
