simplify (x-1-2sqrt(2))(x-1+2sqrt(2))

simplify

(x - 1 - 22) (x - 1 + 22)

x^{2} - 2 x - 7

Solution steps

(x - 1 - 22) (x - 1 + 22)

Distribute parentheses

= xx + x (- 1) + x \cdot 22 - 1 \cdot x - 1 \cdot (- 1) - 1 \cdot 22 - 22 x - 22 (- 1) - 22 \cdot 22

Simplify

xx + x (- 1) + x \cdot 22 - 1 \cdot x - 1 \cdot (- 1) - 1 \cdot 22 - 22 x - 22 (- 1) - 22 \cdot 22 : x^{2} - 2 x - 7

= x^{2} - 2 x - 7

lo g_{3} (9 x^{2} (y + 3) - (x^{2} + 2)^{\frac{3}{2}})

\frac{1}{( 1 - x ) ( 1 - x ^{3} ) ( 1 - x ^{5} )}

\frac{1}{8} (1 - cos (8 x))

x (x + 1) d x
