simplify x(x-2-sqrt(5))(x-2+sqrt(5))

simplify

x (x - 2 - 5) (x - 2 + 5)

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

Solution steps

x (x - 2 - 5) (x - 2 + 5)

Distribute parentheses

= x (xx + x (- 2) + x 5 - 2 x - 2 (- 2) - 25 - 5 x - 5 (- 2) - 55)

Simplify

xx + x (- 2) + x 5 - 2 x - 2 (- 2) - 25 - 5 x - 5 (- 2) - 55 : x^{2} - 4 x - 1

= x (x^{2} - 4 x - 1)

(x^{3} + 3)^{6} (3 x^{2}) d x

ln (2 x) (x ln (3 x) - x)

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

\frac{- 4 - 3 s}{( x + 1 ) ^{2}}

(cos (x) cos (y) - cot (x)) d x - (sin (x) sin (y)) d y
